The game is what it is.
It's simple but not very entertaining.
there are some problems that are needed to be addressed.
1. you can walk a little bit outside the scene, this should not be possible. make it so that you can't exit the screen.
2. you can buy the same item multiple times but it is only the first time it does something except for taking your money.
3. 2x speed is too fast and makes it too hard to control the player.

other than that the game would need polish. sound effects, better UI and better game feel...

otherwise, it has a cute style and a beat-up music track. nice work!^^
