Simple gameplay loop, but it works! I like all the pushes flooding the screen!
It did take a little while to really understand that you had to alternate A and D for me, stupidly enough - might just be me, I do feel like an indication of whether you were pushing or pulling would've been neat!
Other than that, I do like that you give the player some options to choose from when buying! (personally I always went more points since that seemed to scale pretty fast!)
Did get the golden star after playing for a bit!
