Not having a menu or introduction did this game a massive disservice as I died many times at the beginning not knowing what was going on. For a runner style game, the mechanics are fine, but there were multiple instances where I died due to the level not properly communicating where I was supposed to go next (Like at the beginning where I didn't realize I was supposed to duck, or a blind jump pit. The end free-fall was fun, but also very hard to see what was coming ahead. (2)
The art and presentation were pretty simple. I'm glad you made your own art, and the beginning "cutscene' where the character flails was fun. The skulls properly communicate that they are death, and the coins as points work. Otherwise, the game doesn't have much art to speak of. The sound effects were grating, however, and the fact that the character swears when they die has some level of comedy to it but gets old and crass very quickly. (2)
The game doesn't have any interesting unique mechanics, and it doesn't really connect to the theme. The connection that does maybe exist only acts to harm the game. (1)
