Hey hey ~
I think you made some good selections for the music and visuals, they paired very nicely with the gameplay. I had a lot of fun trying to beat the high score you posted - I got pretty close but couldn't beat it :).
Was there a way to reset the game once you've lost? I had to quit and reset every time I wanted to try the high score game, I wish I could've pressed "R" or something. I also felt the jumping felt a little fast. Sometimes I would accidentally skyrocket through all the platforms because I held "W" for a bit too long. I think with some refinement it would feel a lot better.
I really wish I had another person to get the full experience, but alas. I think what you made is really impressive and I appreciate that you did include a single player experience. I had a lot of fun trying to beat your high score and think this game was really cool. Well done :)
