Congrats on finishing your game!
These sort of programming games don't quite land for me and I can't figure out why. I love the problem solving aspects, but a lot of the times I don't feel like there's the right amount of information. The handbook/rules thing here was way too much information upfront, but it seemed essential for figuring out how to even play the game. And not being able to page back through it was frustrating, especially when unlocking more pages. I wanted to trial and error thing, but the '?' blocks kept throwing me. Do those rules change every time? It felt like this game was asking the player to re-solve for the same problem every puzzle, instead of letting me build on previous knowledge to feel like I'm learning or progressing.
The music in the menus was great, but the actual gameplay music was way too distracting.
The art and presentation were nice though. The sketchbook vibe was a nice touch. The monochromatic display portions were a little hard to figure out... I can't tell if I was missing important information or not.
I feel like I'm being too harsh. This sort of puzzly game is really ambitious for a jam, and you clearly have a ton of content. Perhaps testing, refining, and making the learning curve easier to get into would have helped me stick with it more than the first two blocks.
Keep making games!
