Oh, and please do let me know if you get to the end ! we spent quite some time on the final sequence. It's right after the very first (and only) "challenging" puzzle (I hope the challenge comes from the level design and not from our poor implementation of a seesaw)
I thought the light-electricity-rain-magnet puzzle was interesting and intricate enough to make a fun challenge. Part of that was figuring out the mechanics, but it was fun doing so. Perhaps with more levels/puzzles it would need something more intricate eventually as you said, but for this it was a fun level of difficulty.
I did get to the end! The seesaw puzzle was well implemented I think. Maybe a little finicky with the timing of when the sheep counts as being on it, but nothing too bothering.
So you got to the end and saw our little easter egg ! awesome !
I think you were luck with the seesaw, in the game's final state it seems to be still possible (unlikely but possible) to get softlocked there. Anyway, it's not our proudest design, we believe for a puzzle puzzle to be good the solution should be hard to find, not to implement...
