Really enjoyed Ad Fundum. Each stage having its own music gives the game a nice sense of variety, and I especially liked the little secrets tucked away, including hidden achievements for using the radio and taking the time to chat with everyone. The multiple endings add some nice replay value, while the tech tree progression for both the mech and HQ feels genuinely satisfying. I also appreciate the difficulty range, from hardcore all the way down to easy, so there’s a good challenge level for different players. Overall, a fun game with plenty of little details to discover. Would definitely recommend it!

Old flash classic reimagined. If you happened to play flash game called Motherload back in the day, and are looking for a game to scratch the same itch you just found it - Ad Fundum is a great successor to that old gem of a game. I didn't play the demo, grabbed the game at the tail end of sale and went in with expectation of similar game to Motherload, maybe a 1:1 recreation but nothing more. To my surprise this game delivers, beside addition of temperature there is a number of upgrades, scattered across multiple biomes, each occupying specific depth. The mining is almost perfect, there are few minor places to improve, such as ability to move without digging, since manoeuvring around hazards happened to kill me - mining kind off snaps you to a block, and when you want to go into a hole in front, of you, you might mine into say lava on the wall beside the hole. - I did die few times to this. The save system is simple - game saves whenever you go to surface, and you will do it every +/- 30 minutes to avoid earthquakes. There are few easter eggs too, I got a chat for going crazy with the beams (that prevent your tunnels from collapsing). The game has many settings to tailor your experience to be as relaxing or challenging as you like, there is a lot of upgrades for your mech, good albeit minimalistic story with nice art... and even new game+, which I did not expect, but at that point game turns into almost-god mode. It took me roughly 22 hours to get full completion, I only needed to look up one achievement. I highly recommend, I would have bought it for full price knowing how good it is.

It's a better version of Mother Lode, the old flash game banger. 3 hours in and I feel like I'm less than half way. Great level design, super good pacing and it's got good upgrades, priced just right to get that 'one more run' syndrome.

If you're looking for a game similar to "Super Motherload," "Ad Fundum" is, in my opinion, a better version. It does many things similarly to the aforementioned game, but offers several improvements, more variety, and some quality-of-life enhancements.
