Nice platformer. I enjoyed the mystery of what's behind the door at the end of each level. I also liked the clean and simple art style, and the little effects on the laser lines. Some critical feedback:
- SFX felt a bit too loud compared to the chill quieter music
- it was too hard to tell whether a dark purple platform was on or off (colors were too similar)
- the text at the end of each level didn't fit the art style of the rest of the game
Overall though, good job!
