I think we were playing each other's game at the same time. :-) It is a nice platformer -it is quite hard to make one that feels good because there are so many, and people are very demanding and it takes a long time (that's why I never tried to send one for a jam)!
This one properly fits the theme of scaling up and down, but as probably you have seen, many people have chosen to send similar things. I would encourage to keep tweaking your game after the jam to make it more juicy and polished, with things like: smoother animations or with more feedback when using the glass (e.g. a tween to change the size), tighter controls (a keyboard only binding, maybe? Go crazy with feedback: screenshake, larger animations, etc) and jump tuning (gravity doesn't feel great). My guess is you didn't have the time to tune those in 48 hours (something similar happened to me), so I'm not having them into account for my rating. Also more levels with exploration of interesting combinations of the main shrinking and growing mechanic.
One thing that I think you have is your great humor. Please keep exploring that. I checked your other games and while they were not as technical as this one, they were very creative. I would like to see more like those, with the same style!
As a tip, try if you can also the Godot 4.3 single thread web exporter, it went much better for me this time, and may fix user's problems with some browsers!
