Thanks! Right now the solutions are hard-coded into each level. Unfortunately, there are two levels -afaik- that have solutions I overlooked.
For the tutorial level, I wanted to allow the player to only be able to do the solution presented to them; as it teaches the core mechanic of the game, but I didn't have time to implement that so as of now you're able to do both but only one is accepted :(
Thanks for playing and for your detailed feedback! :)
