I really like the idea of having to buy your powers back!
I'd agree with some of the comments about the shop. I think the mouse type control and lack of feedback as to what had been purchased was the biggest issue.
It might have been nice to have the game start with the powers though, and then have them stolen, so the player knows what theyre missing. Would have been a good story opportunity.
Music/SFX was good. Very authentic
Nice work.
