Wow! There is a lot that I found impressive. So many different characters was awesome, different levels was awesome, and the easy yet difficult one button mechanic was pretty well done! Not to mention the AI works pretty well! I love the art and audio as well and think they mixed very well together!
I played a couple games where I started on the bottom and got hit out right away, which from my perspective makes me wish there was a "pause" or "restart" function!
Good fun :) I hope I can play it someday with the actual pump!
