So, I liked the idea, it was pretty original (at least for me), the visuals were a bit weird at first, but you can get used to it. I also liked how you placed the little bits of tutorial and you had messages (like the reminder about the battery) that the player had to unearth during gameplay.

The controls were a but unintuitive, you can get used to it, but at some point I just wanted to dig straight up back to the buy stations, but could not get past a point. You could also make it altogether a bit less dark so the player can actually see things while still indicating the something is dark and therefore dangerous with desaturated colors, feint blue light, etc.

I'm not sure about the many typos. If it was unintentional, I'd recommend someone proof-reading your texts. If it was intentional, I would advise against it, because I think it's okay if a character speaks in a weird way, but tutorial instructions are supposed to be clear.

Overall, nice idea and pretty complex compared to the limited time you had to make it. With some smaller improvements and polishing, this can be a very fun game.

Game was a bit challenging.  I didn't figure out how to refuel my battery.  I think bouncing back on destruction of a block is jarring.  I think the progression of seeing most of the level before diving into the mines is better than starting deep in the mine and trying to find oneself around.  Maybe have a hint arrow/indicator to where the resources are would be helpful.  I felt having gravity was kind of weird at first.  Also, the end game amount is kind of impossible to get given how challenging the game is.  I like the audio and graphics especially the resources flying up towards the camera.

Good Game. Had fun playing it.

Wow the mining is fun in this thing! Really liked the mining and how the collected ore flies off the screen!
