This game could be a lot more interesting if you only game it a clearer loop. Right now, I feel like your game is having an identity crisis. Is it a puzzle game? I never once had to stop to think about how to do the level, it was just teleport, go to key, teleport, go to key and so on. Or is it a dodging game? If not, why are the spikes there to slow you down? If you just chose a direction, the game could go far, but right now, it's stuck in some kind of middle ground where you don't get either of the experiences. The art was great though! Some things I thought about:

1. In the third level, there is no number over the door indicating how many keys you need.

2. The spikes seem to stutter when they go up and down, its not a clean on-off rythm

3. There are a few typos in the quotes, they kinda ruin the whole wise words thing.

4. There is no music. Just a tiny bit can go a long way! Also the bleep of the player moving is really annoying.

(Please take pity on a poor soul who couldn't port his game to wasm and go play my game Grandma's Garden here: https://sixten-bergman.itch.io/grandmasgarden)
