I quite enjoyed this game for what it is right now! I like that it is difficult, but a small hint or something to point you in the right direction would be nice sometimes. I liked the idea of using items to obtain other items, and the "portals" to get other items you'd need.
Only downside: The interacting could be a bit better. When you'd interact with a painting on the wall that does nothing, the item you were holding drops. Kinda annoying, but that's the only thing that could be improved.
I'd rate it a solid 4/5. Please continue developing this game! It definitely shows potential :)
