This is such a fun, cute game! I could probably play it for hours. The puzzles are clever and the difficulty curve is really well done, with each puzzle building off the last - great work! I definitely didn't realize the orange sprite you "become" was meant to be a mummy that the player-character is cooperating with; I thought it was some kind of helmet or portal somehow. It also wasn't super clear -why- you had to "become" the orange sprite to move from one level to the next; if there was a specific barrier that only that other sprite could go through, it might make more sense? Didn't impact my enjoyment of the game at all! Before reading your description I assumed that the role reversal was in how going through the blocks made them impassible, and having to work around that, as a trope reversal from usual platforming/dungeon exploring games (where normally you have to worry about falling and hitting obstacles being the puzzling aspect). Great work!
