I've completed the game in its entirety (not including the secret levels). Honestly one of my favorite puzzle game fangames ever.
I was thinking about making a full solutions walkthrough on youtube, since basically every other puzzle game has walkthroughs and this deserves one too. I probably will but idk, i'll have to see.
Here is a link to my hint list, since it hasn’t been posted in a while: https://itch.io/post/12746349
Looking at a walkthrough for a level you are stuck on is a slippery slope that quickly leads to looking up the solution for every level that poses some resistance, even ones you could have solved. Imo its better to make this process have a lot of friction so people don’t readily use it, by making them scrub through a let’s play (one exists) or have to ask and wait for a reply.
