I think I spent an hour on level 14
Apart from that the ideas is fun, some levels can be quite tedious, and I found myself noticing that some of the levels looked very similar (levels 3 + 8 and 5 + 7 + 9), at one point i thought i was doing the same level, or that the levels looped, there's nothing entirely wrong about harder levels that resemble those before, but giving them some visual distinction, or as a bonus levels thing might fit better.
Oh no, I hope you made it in the end :D
Yeah, tedium is definitely a bit of a problem, still gotta figure out how to design the game / the levels to avoid that more. And yeah, I'm a firm believer in non-linear level structures and optional levels for puzzle games, so if I should continue this, I'll most likely add some sort of overworld and branching paths. Even so, I guess there's a good change 80% of the current levels will be scrapped and replaced.
