Thanks. I like the idea of a step counter, I wish I'd thought of that! as for a level selector, I don't have enough memory left to really add something like that, sorry.
No matter, the game still was a blast, and thank you for the wonderful distraction! I especially loved the places (mostly near the end of game) where the player has multiple choices to choose from, but it's flexible enough that there's still multiple ways to solve the level, not just a strict "THERE'S ONLY ONE CORRECT AND TRICKY SOLUTION" that most of the puzzle games tend to stick to.
