While this adheres to the theme by only being able to carry only one key at any time this has NO gameplay consequences since you can always backtrack to get any keys laying around. Thus there is no difference to just having them in your inventory.
This means being able to only carry one key is nothing but a annoying gimmick.
Other then that I quite like the maze like puzzle character of this game :D.
One of my personal favorite games of the jam. But then I did also enjoy "The worlds hardest game" and I am a little bit biased towards puzzle games. With a couple of more difficult puzzles to solve I could totally see myself wasting a couple of hours playing this game while I should be doing productive other stuff :D
Nice game. I personally don't like cookie clicker but I tested it anyways xD (not without the help of an AHK script though) and I must say I find the idea of having to balance two things quite interesting. With more stuff going on simultaneously and some kind of time pressure (maybe people retracting their invites or something) this could potentially be quite a fun hectic game :D
Nice idea. Feels good. Personally I wouldn't add the fruit models. It is clean and elegant like this. If you plan on working on this more then just work on the difficulty progression / maybe add some more mechanics you can play with to create interesting puzzles. E.g. movable rails, no wrapping, color walls (you can't move colors through those / the rails block)
A take on the classic line drawing / connecting puzzle game. I've always enjoyed these a lot. It seems you got the main concept down. If only there were more levels / some real puzzles. But then puzzle design can be quite difficult.
That being said you said you wanted constructive criticism. Obviously some nice clicky sound effects would add a lot :D. But yeah all in all more levels / proper puzzles. There are some fantastic talks about puzzle design hit me up on the discord and I can send you the links :D.
