This game was great!
The realm switching mechanic was fun to shift in and out of, and the platforming itself was also fun and pretty challenging.
The few suggestions I have would be to for sure add some sort of checkpoint system, as the game got a little frustrating at times, and maybe let the player switch/cancel out of the ethereal realm, instead of having to wait the 5 second every time.
Overall the game was fun and well designed, sucks that the upload messed up.
