That's a cute style and nice palette! I'd call it "Something Undertale-like, only with neat drawings" :D
You have a cool and smooth camera work but I felt betrayed when I jumped off a cliff and landed on an enemy which I didn't see :D
I think you could reposition camera to show upper platforms more to show player that they could reach it with their jump.
Also, you could add some UI with "exiting" from stations and chests. I pressed everything and then I figured out that I needed "Escape".
I suppose gml error in the end at the hitbox_dicer_obj was the opportunity to exit from the game :D
Maybe I was trying to be too practical and trying to minimize the failures by getting the whole dice together, and then I would already roll myself whatever I needed.
I really liked the style and music of the game. Your music was enjoyable and didn't bore me at all, well done!
