I can tell this is a puzzle game with a lot of passion behind it. I really liked the mechanics you introduced in the tutorial, and you show a lot of fun ways they interact right from the start. 

I believe the game itself could communicate to players a better sense of game progress. It's a little obtuse, overall. Like on the pause screen, you can still move your character and shift between worlds, but it seems to distract from the actual functions of the menu. (I was confused a bit at first what the circles and lines meant, before I realized that made the map of the game). I don't mind the idea of doing that for a map, but combined with the pause screen makes the idea behind it a bit muddled. 

The camera also could use a bit of polish. I didn't realize at first it was swapping between levels, and was a bit afraid to progress because I wasn't sure what the next space would hold for me. 

Lastly, the game could use a bit more visual cohesion. Assets seem to be at different pixel ratios, and that can be a bit distracting. 

That all said, I'd love to see what the polished version of this game looks like. It's got a lot of passion behind it and you've shown you can use the central mechanic in interesting ways. Glad I got the chance to check it out! 

I really like the gameplay concept, but I keep forgetting to switch realities and dying,

Also, it might be better if the music didn't restart during minor scene transitions, like going from the main menu to the settings menu.
