Amazing game, one of the best entries imo. The player controls are fantastic, the aesthetic of the game was beautiful, and the take on the theme is very clever.
The spawnpoint system felt very inconsistent to me. Often it wouldn't create the spawnpoint and I wouldn't realize it until too late x_x, which would send me back to the start of the level. This was pretty frustrating. It even happened twice in a row to me (sending me to my previous spawn point and then the start of the level) causing me to audibly "bruuuh". Unfortunately this is what eventually killed my play session prematurely, so I didn't get to complete your game.
Some audio and visual feedback when the spawnpoint is set would be nice. You can't tell it until you move off of the position which lead me to some confusion the first time as to whether or not it worked (causing me to click three more times looking around for some kind of feedback).
Enemies don't look like enemies. I initially thought they were friendly and was going to try and interact with one until the text corrected my assumption. This was confusing and a little odd throughout the play session.
I couldn't tell when I was and wasn't able to collect the little collectables. Sometimes I could see them in both dimensions, but not collect them in the one that I was currently in. At first I assumed I could only collect them in a specific dimension, but then it happened in the other, so I just started ignoring them.
