Really visually stunning and unique mechanics! The only things I have to critique are the controls and a bug I encountered. I noticed you teleport when you are clicking the teleport button *and* when you are clicking the shoot button. I think it'd be better to keep teleporting to one button only (and possibly move it the keyboard instead of left click just to separate those commands a bit). This would make it so that you can teleport then continuously shoot from one location without having to move. I feel like this would speed up gameplay and give you the freedom to make enemies more dangerous/quick since you can shoot multiple times from one spot.
I also managed to glitch through the wall of the first room and outside of the cactus-enclosed map which caused the timer and enemies to disappear - granting me the potential for an unlimited score >:). As a result I was permanently stuck and had to manually shut down the game.
Otherwise I think it looks super clean and professional and I could 100% see this as a mobile or pc game. Nicely done!
