Loved this game! Took a couple hours, but I finally fully completed it. My only complaint was that some of the transformations and their iconography are not explained anywhere. I had to actually go into the source code to figure out what the three dots was referring to, for example. Thanks for the fun!
Thank you for playing the game! I wasn’t expecting many people to score 100% completion. :D
The three dots thing is there to keep some things cryptic on purpose, so there is some exploration and experimentation left for the player. It’s usually possible to finish most of the levels without a full understanding but the combined puzzles (the ones that unlock the bonus levels) require ~full understanding of everything. This is a bonus (optional) content, so I felt that it was fair to keep it challenging. :)
