3 stars because atm, when they say prototype they really do mean exactly that, a prototype. It isn't even really much of an alpha at the moment. Can reach the end of content within 5 minutes~ and it's not even clear that it actually ends. Only realized when I read a comment below by the dev.

That out of the way, the game seems like a solid concept and has potential, it could end up being a solid game as it develops, we'll see.
