I've been playing Soulslikes for a long time, so it takes a little more than just belonging to that genre to impress me. Lunarium managed it right away, though, and the first thing that pulled me in was simply how gorgeous it looks. But what's even more impressive is that it somehow keeps getting better as you go. Instead of showing everything up front, the world expands, the characters grow, the combat deepens, and even the difficulty feels like it grows along with you. There's a point where you defeat a Starfarer with this massive Knight Blade. I won't ruin how it happens because that moment really matters, but eventually that weapon becomes a core part of how you play. And it isn't just, "here's a cool drop for winning". The blade has meaning, and using it carries that meaning forward. It tied me closer to the characters, and by the end it plays into the story's resolution in a way that felt fully earned. The final boss was tough, the toughest in the game for me, but it wasn't difficulty for its own sake. The build-up made me care who I was fighting, and the presentation was stunning. It gave me that rare feeling of finishing something and thinking, yeah, that ended even better than it began. I came for the art. I stayed for everything it built on top. The ending really makes or breaks a game for me so I honestly have to give it a 10/10. This was a game I wasn't following at all, wasn't aware of at all, and yet I genuinely enjoyed the game and it's story the entire way through.

This is a slick, well-made action game. The combat is great, the world is pretty fun to explore, the visuals and animations are outstanding. The "story mode" difficulty option can be toggled on and off at will and it doesn't completely trivialize it. Strong recommendation. The one issue is that this game has roughly 10x too much dialogue. I imagine in its native tongue it is eloquent and beautiful, but the English localization is inconsistent and boring in a lot of places. It's got some sweet moments (...I think those girls are more than friends) and it made me laugh out loud a few times - but damn by the end I had to skip many of the exchanges and I wanted it to be over.

A somewhat flawed experience due to how finicky parrying can be, since the combat relies on it a lot. Dodging is perfectly effective too and can do the job most of the time, though. It feels somewhat fresh to see a game like this use an isometric perspective, and the levels look quite gorgeous and are fun to explore and search for secrets in, so it's worth mentioning that in this area the game does particularly well. The story's surprisingly enjoyable too, with likeable characters and great art. The English translation's not terrible, but it lacked enough proofreading as you can spot a couple mistakes here and there. They're apparently improving that by patching. Performance's great, which is a relief considering it's a simple looking indie game made on Unity. Overall, I'd enjoy seeing this studio further refine their game design by taking on a sequel (be it Lunarium 2 or just a similar game) with refined combat mechanics and a better balanced challenge. The toughest boss in the game took place by the first 1/3 of the experience, and after that my player character steadily got too powerful for bosses to provide a proper challenge.

Edit: The devs were super fast to correct the issue concerning the Crimson Dancer boss, so I could go on playing the game until the end, with no more bugs / defects happening along the way. I think I enjoyed much playing Lunarium, as well as it seems to be the case for many other players - for a first essay it's safe to say that it's a pretty successful one. I do have some minor inquiries, but which didn't spoil the pleasure to play it - such as, at some point the difficulty significantly spiked up with some latter bosses, which kind of ended up forcing me into choosing the story mode difficulty; and to be honest I wish there had been an intermediate difficulty between the normal and the story mode one, this last one being a bit too easy imo. I also wish that some things (item locations, mini-bosses, path to take etc) could have been a bit more clearly indicated, not to hold the player's hand, but because some items could be really tough to find, as well as the game's final stages confused me a bit as for where to go and what to do - it's also good, because it sort of coaxes you to explore the game, but it may also prolonge its playtime in a bit of an artificial way. These inquiries set aside, I think that the Lunarium devs did a great job with their game, which is most apparently a game in which they poured much love, as well as it was very satisfying to see their reactiveness in front of the players' inquiries. I felt various sources of inspiration as for Lunarium, like Hollow Knight for the music, or Nioh for some elements of the combat system (the red counterattack), and the challenge the game offers is really satisfying for a souls-like veteran as well as for a less confirmed player, regarding the chosen difficulty. All in all it was a little but true blast playing it and I'll be expecting with much interest what these devs will be preparing next. _______ I wasn't waiting much of Lunarium, just an indie game to crunch between two other 'big' titles, but the game surprised me in a most positive way. The pacing and difficulty at start are rather low, then spike up pretty quickly while staying manageable, the map is varied and detailed, with a lot of secret rooms and items to find along the way, and I found the art, the cell shading-like graphics and music (even if the main theme gets rather repetitive) gorgeous. I however ended up coming across a game breaking bug with the Crimson Dancer boss, forcing me "into the table" without much of any other viable option. Leaving a positive review as I was impressed by the game's quality, and will go on playing and update / expand my review if this issue is resolved. Excluding the various periodical bugs, excellent job overall.

The GOOD Straight to the action and no lengthy intro, learn-as-you-go gameplay. Beautiful hand-drawn graphic to explore and traverse with it's lovely soundtrack. A very wholesome coming-of-age story of a young knight and starfarer's journey to save their home. The Gameplay The game is not hard, just the classic of "trial & error" and pattern recognition. There is a lot of non-interruptible action, so combat is about managing a well-paced tempo of success. Conclusion It's worth buying and supporting a dev who makes games with passion.
