Thanks for the long list. I give you my in return -
Many of the things and limitations you mentioned (especially the SFX), were omitted because of the time limit, as this is only my second game jam and I am not so good at time management. The trees in the overworld you mentioned were from a free asset pack, so there wasn't much choice. The aesthetics in some dreams feels different because I wanted to make every person's nightmare distinct and very different from each other, as that's what happens in reality.
Yes, the maze has an end. The dead ends are actually very few, albeit longer. The side-stepping burger part wasn't intended initially but I got into some problems in between, hence the "improved" version. The end timer suggestion is really good. I never thought of that.
I am very poor in handling sounds, but I am trying to improve day by day.
First bug is there because I didn't do looping on the background sound (Forgot in a hurry, submitted 15 seconds before the end). I'll look into the last two.
This got a bit too big (Have a taste of your own medicine ;)).
Jokes apart, I will honestly try to implement as much as I can, maybe even more, if I continue it. Thanks a lot!
