Cool quest! I love it when someone else makes jam quests.
It’s really good that there’s a goal and progression in the form of three tasks. This allows you to clearly understand what to do and whether you’re moving in the right direction.
It would be great if the puzzles were more challenging. For example, more items or logic mini-games. Or, for example, if the equation for the code were regenerated upon restart.
By the way, I also have a point-and-click quest in submission.
Associative chains work well for puzzles in quests. I recently made a small abstract game purely based on associations – by color, shape, symbols, arrow directions, wire connections, etc. https://maximkolesnikov.itch.io/5buttons
