Man, I really enjoyed your game! It was a lot of fun getting through the traps, and finding the rocket provided a different and interesting way to play.
I only found one bug, but it definitely doesn't make the game bad—it's easy enough to just not use it. When you press the S key, the player gets teleported very close to the end of the game. After noticing that, I restarted and played through the entire game from beginning to end.
Congratulations, it turned out really well! I believe that bug was just a small oversight that happened during development. It's nothing that ruins the experience if you play normally.
Great job! :)
