The game is fun but very difficult, part of it because sometimes when I was about to hit a mole , the buy screen popped up, when the game resumed the mole would instantly go back to their hole.
The moles also seem to spread really fast, even when using the power ups. The concept of using powerups or saving your money for later is also a nice touch!
The game has nice visuals and sound, although the holes are noticeable objects on top of the texture, maybe make them fit in better with the rest of the visuals.
Overall good game, nice work!
