I love your title screen, more games need to do this… show some character some of what the game actually is (specially if arcade-y like yours) on the title screen. high marks for that one!
the gameplay is quite simple but well done, the grow/shrink pads makes sense with the theme, the score being a tug of war instead of flat points is also interesting.
as points of improvement:
- the most important thing by far: pay attention to sounds being played too often, there are quite a few cases (both on the title screen and in game) where you can trigger a bunch of collisions with the ball and each play the sfx, which makes it be a super painful loud noise
overall good job, hope you had a good time making it
