I actually figured out what the issue was, it turns out you can't launch the game in the itch.io app because it won't launch the debug window, so pressing enter on the game window doesn't load a level. But if you open it from a file explorer it works, and all the levels worked fine for me! However, I had a bit of a hard time moving the camera to a middle point vertically on the screen because the slightest tap would move it straight up or down. Otherwise it had great music and a cool feel! Here's a link to the stream clip where I played it: https://www.twitch.tv/videos/1494126580
The camera movement issue is caused by your CPU being too fast. All the other movement multipliers are multiplied by the frame delta time (so that the movement speed is the same on all CPUs), but I forgot to the same for the vertical camera multipliers, I just uploaded version 0.9.2, which contains a fix. I also noticed you were using v0.9.0 in the video, even though the latest version at the time of recording was v0.9.1.
