Amazing game! The only thing I might suggest is that maybe instead of coloring the player black after teleporting, maybe color them white? Because the dark background makes the player hard to track sometimes, especially in the later levels with all of the midair teleports you have to do. Still, other than that minor thing tho(and maybe tone down that 1 spike level (level 7 if I counted correctly) because I died way more times there than the other levels), I think this is a really spectacular game! Stellar work!
