I really wanted to push through with this game because I love the portal-inspired design and puzzles, but I accidentally closed the tab on 2 separate playthroughs whilst crouching, so I had to download the game. I’d recommend either warning people about this on your page or setting c as the only crouch button.
I also agree that the first cutscene needs to be either shorter, skippable, or the player needs something to do during that time.
I seem to be in the minority of people that really liked the visuals here - the RGB effect at the edges of the camera looks very good.
Puzzles were interesting and varied - some of the platforming sections really made me concentrate to get through.
Overall a very good submission, well done
