There was some fun puzzle-solving in this one! Splitting into two people was unique.
Some of the puzzles felt kind of random like dying to spikes off screen.
The platforming camera lags behind the character's vertical position when jumping which is normally nice but it should make sure to show the player the ground on their way back down. Blind jumps aren't super fun.
The spikes could be made more visible and attention-grabbing. I died to them a lot because I didn't know they were there.
The doors just kind of stood without any kind of building behind them looked kind of strange. It doesn't affect gameplay but might have been nice from an art perspective to have buildings behind them and maybe have doors with connected functionality on connected buildings in the background.
