The lighting and atmosphere is nice! There were some issues with the game pausing after pressing restart and space. I feel like restart should take you back to the beginning of the room instead of the entire game since it feels a bit punishing. The rewind block works for the most part, though stage elements don't seem to rewind their visuals so it appears like I clip through lasers and doors. I think the player should be able to move into the keys and buttons without having to collide with them.
Overall, this has been well done!
