Jan. 2026

Had this game on my radar for a few years now and finally remembered to get off my ass and pick it up. I think this game is really cool and has a LOT of potential, so I wanted to write this review to give some positive and negative (constructive!) feedback on what I see. Please note I don't really do reviews so I have no idea how I should be doing this. Firstly, I want to disclose I came into this game with the "no way it's JSaB with a level editor" mentality, so I think that constitutes as some bias you should keep in mind. POSITIVES: - I genuinely LOVE the flavor/aesthetic of this game. 10/10 I am a huge sucker for trippy computer stuff no notes. awesome. and flashy i like flashy. I love this a lot. - Controls feel straightforward and pretty responsive, which makes the game feel pretty easy to learn and improve at. - Soundtrack is solid so far, I think it fits the vibe of the game a lot but is still diverse/unique enough where it still feels rhythm game ish (if that makes any sense). - I'm very intimidated by the level editor but it seems pretty powerful so I'll trust what I see there :> - Story seems promising so far, but I might be biased with the aesthetic (though I suppose the presentation is a part of the storytelling, so is that really an external factor here?) - Sphere is my favorite official level, it really shows off the full potential of the game's official levels and it makes me really excited to see more. I also like how it sorta resembles a virus or something considering the lore being about training simulations to cure diseases. NEGATIVES: (PLEASEPLEASEPLEASE don't take this as hate or slander or anything else, nor as me acting as if I'm some objective paragon of game design. I'm not a professional, I enjoy this game, and I aim to be constructive and provide my raw feedback in hopes some of it is useful): - I'd like to see some more visual feedback for the dash, especially because of the variable distance. It's a little difficult sometimes to tell where my iframes are, especially in chaotic or zoomed out maps. I would love to see a setting or something for some sort of "high contrast dash" or something. - I wish the first four story levels were easier to replay on demand without having to replay the whole intro (or if there is an easy way, I wish it was communicated a little clearer). - The save files/slots/states feel a little confusing at a glance. I think that's user error on my part, but a little less clutter or a little tutorial in the menu would go a long way. - Accessing custom levels is an absolute pain and ruins my motivation to try new ones. I did see on the Discord server that this is already fixed in the Alpha, so I don't think this needs any more elaboration :) - The EASINGS... I see the value of the easings on a lot of attacks and movements and such as a style choice and I do quite like it, but I do think that there is a bit too much in some parts. I think the easings are good generally, but sometimes it messes with the sync in my head. I would love to see more "punchy" easings/animations thrown into the mix, but I also understand if it's a style choice. - I would really like an option to restart a level from the last checkpoint instead of the very beginning for practice! I find myself missing this type of option a TON and I think it would be a very helpful QoL feature. Overall I really really like this game and I hope my feedback helps in some way (or at least I hope it doesn't sound like an entitled JSaB player rambling), I look forward to the day the full game launches!

This game is a fan game of jsab with pretty much all community made levels. I will say that it feels less polished than jsab, but in terms of the levels, I find pa more fun to play.

Oct. 2025

After doing literally everything in JSAB, i got back to this game. It had 2 cons for me: bad optimization and dash/boost mechanic, but first i kinda solved with overclocked AMD Ryzen 7 9800X3D and second, the boost mechanic got changed a bit and i got used to it. Some levels can give a challenge even for experienced JSAB players, like me, and personally - i like it. P-ranking Master levels are miles harder than S-ranking Mortal Kombat in JSAB, (which is considered the hardest level in the game by the community) For those who liked JSAB: PA is must have. Might take time to get used to boost mechanic, but this is worth it

May 2025

AWESOME GAME!!! it's jsab but community made levels and more colors!!!!

April 2025

So I've only played this game for about less than an hour and I have alot to say... first of all, I love the gameplay and story mode just from the intro, I'm a JSaB fan and this totally fits the style, but even better. although, you may want to add an photosensitive option in settings, as I couldn't find one, also the selection of languages is a bit minimal, I know the game is in early access, but when its fully released, at the least add French, Spanish, German, and Russian. you'd be suprised how many countries outside of Europe and North America that have these for native language and struggle with English, could be more appealing for other users and boost interest in game. just dont add languages that exists in few areas (yes, Im from Norway and I can confirm its unessecary to add Norwegian) also when game gets full release try to add UI that shows controller controls when you play on controller. in general I would recommend this game to people who are fans of JSaB, Super Hexagon (yes there are songs from Chipzel) and custom levels in Geometry Dash. goodluck with the project.
