This game seems promising, but I have some issues with it
The movement and looking around aren't as responsive as in ultrakill for example (possibly because my machine can't run it that well idk)
Also I wish the healing system was a bit nicer, having to go touch a static ball is difficult to do in a combat scenario and it doesn't really make much sense (why they are decomposing into orbs i mean)
The terminal is nice, but I feel you could convey lore in a less reading-heavy manner, letting the player explore the world more instead of just reading about it
Also the visuals are a bit bland, kinda seems like ultrakill but in a mine
I hope this hasn't been too hurtful and hopefully you can consider what I've brought up and make your game the best it can be! Good luck
