Thank you for your feedback!
Terrain-destroying mines are a great idea, but with the limits on oxygen, power, and visibility, I don't think it would be work/worth it just to find hidden treasures.
In the current version, the game lacks a smoother start and mechanics that reward exploration (some of these are already implemented, but you have to play for too long to reach them in a game jam). It definitely needs more content, but within this short time period, it wasn’t possible to add more (I couldn't even balance it in time)
