This is a super fun game. 

To me, the best play was to start safe (building stairs, getting back to the base) until I got to the yellow coins. Then, I would always go as deep as possible and get as much resources as I could and die, respawn with half resources, buy whatever I can and keep doing that until my battery was enough to get the drill machine. Then I got to the end of the game and killed the boss!

I don't have much feedback to give other than maybe a better visual feedback when you hit enemies, but to be honest I'd always avoid them because it wasn't worth to kill them anyway (AFAIK). The drilling experience was super fun, and it's nice that we have to be clever about our digging in order to prevent getting trapped. The powerups make sense, and the music is an absolute blast. This is a really solid entry, great job!

Cool concept, but a little bit unfair when spawning enemies, because they seem to appear from literally nowhere, and they ambush you, i don't know if that was on purpose to make the player stay alert

i defeated the monster and got what i think is lower than i’m supposed to be, and then i accidentally pressed ‘E’ … and now am stuck in perpetual freefall!

or i would be, if the game weren’t cheeseable! at first i thought there was great challenge in finding my way back to the base, but then i realized that refreshing the page maintained my inventory and other state but plopped me back at base. no more lost resources!

I be doing video feedback, I tend to be ramble-y but still its nice to see how far someone gets and what they do!

This was really fun (and the soundtrack slaps) but after you play a while, especially with the more powerful gun, it becomes really hard to maintain a route back. I was trying to be careful but accidentally destroyed a block in my return route and softlocked myself. A jump upgrade might help with that? Overall really nice though!
