At a certain point it becomes impossible to buy something from the Rare Items part of the shop, because no matter how much money you get, both items are always at least $10,000 more expensive than the money you have.
I find it odd that when I was really focused on finding the right way to balance the shapes on level 20, I couldn't do it to save my life. But when I raged and just spammed the shapes on the screen, SOMEHOW they got into a position that prevented any of them from falling...
I liked the concept, but didn't like how much the game resembled a game that you would expect to find on A website with games created for young children. Not in the aspect of the game, but the physical appearance, the music, and the voices. I was slightly deterred by this, however the existence of badges overrode that.
It'd be nice to have some red dots on the minimap so that we can see if there are any enemies left on the floor to deal with, or at least an indicator to say how many enemies are left on the floor. 5/5 though :)
