Annoying

First of all, stop pushing the d*mn in-app-purchase down our throats.
I know you want to make some money but not this frustratingly annoying way. Rather than bugging the players to pay you chunk of money try fixing the physics in this game, the physics are extremely weird and inaccurate.

The graphics look great and got you an extra star.

*Deleting the game since it is not playable "yet".
Fix it.
