Love the idea. that was exactly what Ii was aiming for before moving on to what I have now. However, the execution wasn't what i was expecting at all.
First, I think that this kind of game would work much better separated in rooms, like celeste or portal, so you can have unlimited trials without having to start over every time (which is very annoying). It could also allow you to have special gimmicks per sets of rooms, and vary the gameplay !
Graphics are very inconsistant, you might also want to learn how to fix light flickering and common UE graphical issues, which are very visible in your game (since it has a lot of reflections).
The audio is ummm... the same sound throughout the entier game ? x) An unreal engine default as well, I recognize it.
The player recording works well, apart from a few times.
