I ashamedly haven't played Thomas Was Alone but I'm guessing the intro is an ode to it?
This is probably one of my favorites of the jam. The mechanics are nicely implemented, simple to understand but still tricky to play, like I know what I have to do but my brain/hand coordination just isn't up to the task every time. You explore the mechanics pretty thoroughly too and have a nice difficulty progression. The controls are pretty solid, the floaty character works well, I found the switching to be a bit unforgiving at times which made some levels much more difficult, for example the White Boxes level you have there in the screenshots, that one was probably the most tricky of all. But I got there in the end and I had a good time doing it. Great work!
Btw, I looked up EggAcademy and man I'm super jealous, I wish I'd had something like that to take part in while I was growing up, very cool, I wish yas all the best.
