It's a cool concept with cool mechanics. 7/10

The upgrades are definitely too expensive considering the frequency of materials spawning but overall a really fun concept

Wow, very cool game! I didn't expect to see something like this considering jam only lasted 3 days, quite unique idea and I like it a lot, game looks nice and adding some sort of end goal would make it smth I would like to play in the free time. Though there are some problems, like the upgrade menu feels a bit overwhelming when you first open it and making tiles empty until you dig near them makes the world look a bit empty (maybe making undiscovered tiles completely balck would help) and a couple times game just froze for a few seconds and then all my progress was gone. But there will always be some issues when making a game in such a short period of time, good job, Great game!

Maybe you'd check out my game too ;)

I really liked the concept! Pretty clever game, also kind of addicting considering the shop feature :P

Nice! I took some time to understand it, but I ended up getting it.

neat idea - did not understand what I need to do - shoot was fun

Interesting concept, I like it !

Your game idea is interesting and has potential :) But the controls/movement could use some work.

Interesting concept but it didn't feel like enough materials spawned fast enough for me to get many upgrades and it was kind of tough getting to any particular wall to mine it after I had blown away most of the main area.
