Glad you enjoyed! I’ve addressed the walking in other comments so I won’t do that here. The filler puzzles kind of ended up being necessary in order to introduce mechanics at a reasonable pace. I generally try not to introduce mechanics too fast so the player can feel overwhelmed. I think it really depends on how fast each player ends up picking up these mechanics so that they can play the more challenging puzzles. The puzzles are skippable for a reason, so think of the first ~10 as a build-up for the last ~5.
Also the permanent wires were kind of an afterthought lol, I only added them when I was almost done the game. Tbh I wish I’d planned all the mechanics in advance, but my idea at first generally ends up being so different from the final project that the plans for mechanics I have end up just falling apart. (That’s what happened here).
I’m glad you still managed to enjoy the game despite its slow pace.
