I like that you made an exploration/adventure game!
It's a bit odd that the player is hurt/blocked by some things that aren't in the same dimension, even though you can go through other things. It feels like the laws of this universe aren't consistent. If something can affect you in both dimensions, it would make more sense for it to be visible in both, whereas something that only exists in 1 dimension should only be visible in that dimension.
I wish a couple of the larger rooms could be combined into 1 room instead of being separate. There's a lot of empty space to walk through.
The audio sounds distorted with a bunch of static.
