Is this supposed to be clunky? The graphics are simple but not great, the music is repetitive and terrible, but the gameplay is really the worst. The jumping mechanic is clunky, the physics are awful - in the first level, I landed squarely on the cheese block three times in a row, only to be pushed to the left by a mysterious force and die. The exploding mimes are even worse, pushing you backward off platforms, or having random spiked balls require near-impeccable timing to get past. It wasn't until I reached the invisible platforms that I realized this was a rage game, and that this was explicitly what you were going for (I hope.)
Considering this game is meant to frustrate and upset, it should come as no surprise that people aren't going to like it. I quit at the level with the rocket upgrade and the balloons, partially because nothing seemed to work, and partially because I just wasn't interested in playing more.
