I really like the art as well as the mechanics. My only problem is that I couldn't find the exact controls at first to use the skills. While some of them are passive, some of them also have to be triggered by a key and I had to spend a little while figuring out how to use it.
I'm pretty sure the game is about rebuilding something (maybe a part of the base or the place where the main character is or smth, judging by the 30 collectibles). But still I'd like a more specific explanation.
Nice work, man!
