I like this game! The aesthetic is cool, you even made the game window 4:3 ratio, haha, I enjoy that detail.
The visuals are nice, but there was some confusing things at which buttons were interactable and which were not at first. The icons itself were ok too, but they had different pixel density compared to the background, plus some UI elements were pixelated and some were hi-res, which combined was quite distracting, so a visual update could go a long way for sure. Texts were a little small for me. Another important feature I think you should definitely add is that if the player fail, don't go straight to the losing screen, but let them see their score, so they can know how well or badly they did with their previous solution, so they can adjust. Plus failing one puzzle go straight back to the beginning is a bad UX imo.
Hopefully I didn't sound too negative. I actually enjoy the core concept of this game a lot. It's quite unique and has some cool ideas. It's just that the implementation is a bit lacking to let it truly shine, so I want to point out some things I hope you can fix to make it more enjoyable to players :)
