Amazing game man!! I like how everything in every level served a purpose. Clean and clever lever design :)
I found the later levels super challenging, not so much finding the solution as executing the solution.
If I have any constructive feedback and say make performing the actions of the solution easier, that was it's less of a pixel perfect platformer and more trying to solve the puzzle. Unless that's what you were going for, in which case I'd say, well done!! :)
Either way, sweet game dude. And amazing that you did it in 3 days while also recording a dev log video at the same time. Mad skills!!
