I quite like the idea! The screenshots look like they have a cool outline shader which the web version doesn't have? That's too bad. From what I've seen, puzzle design was decent, though I felt there were too many moments where you got soft-stuck and had to either wait for some cycle to complete or just downright throw yourself into lava. Got to what I thought was the end of the third chamber, but got stuck there (I shot the button which caused a door to close I believe? And I couldn't find a way to reopen it), threw myself into lava and found myself back at the entrance of the second chamber but without a cube. I didn't feel like replaying the entire game so far, so I stopped there. Physics processing for the held cube was pretty wonky, not sure what happened there, and took me a while to figure out the distance from where you grab a cube mattered, which I thought was a little weird, but maybe I play too few first-person games. All in all, this is a pretty promising start and I'd like to see where it goes!

First off, amazing effort for a short jam, big of Portal, so I thoroughly enjoyed the puzzles. From a technical standpoint, most of my complaints are probably just a matter of time constraints, such as having the ability bring the box closer or further while holding. Some of the box physics were a bit funky. But again, short jam. I do think the size shifting would need to be incorporated more in a more fleshed out game. Great effort.

Could not complete, as picking up the cube caused it to wiggle uncontrollably and despawn.  Playing in Chrome browser.
