Amazing game and I predict it will be in the highlight video of GMTK.
The idea is so unique I'm surprised someone could think about it.
The game is very good but not without flaws:
The narrator is too vague in explaining the game, from the UI it is not clear what is each item in the shop.
This may sound harsh but the good stuff in the game far outweighs the bad, and it is a game that I can see myself playing on my free time.
