Thanks for the constructive review!
I agree the level design is preety bad. I should've definetly spent more time on it but alot of the dev cycle was spent on the loop mechanic.
One of the biggest issues with the game design is the difficulty. As you've told me the puzzles are very easy, mostly because of how linear they are but also the time limit being very generous. But from other reviews i've gotten, and some playtesting i've did, some players struggled with the time limit. It's a balancing act and well i haven't balanced it well enough!
