The puzzles were extremely well thought out! I was veryyy much getting portal vibes from each room, so that was awesome. The only issues I have (that I have also faced with my own unreal projects as well) was the looking speed and acceleration, as well as the jumping/flying acceleration where it takes your initial jump’s direction and continues to apply acceleration, even if you try to fly or jump the opposite way (not sure if I explained that properly). It didn’t really interfere with gameplay that much tho since you get used to it!
All in all, it was super fun to play!
