Cute little game! I thought the concept was very unique and funny, and the gameplay was very fun and, while simple, was deceptively challenging to get through. Loved how the levels ramped up the difficulty and introduced a lot of interesting events which kept me hooked all the way through, especially the last level which was a huge gauntlet and ended with a bang. Speaking of those events, I felt like the game had a lot of charm to it: cool aesthetic, slick animations/transitions, goofy failure messages, wild replay mechanic, etc.
I gotta say, though, I had a really bad start: I know it seems obvious now, but when the first level started, I had no idea I had to press space to actually start the level, as my focus was on the instructions to hit up and down. I actually loaded up a separate browser since I thought maybe the game wasn't reading my inputs, haha! Glad I figured it out though as I had a great time afterwards.
