Did you work in a team?
Just me, and a friend who wrote a few dialog.

Was the resolution a challenge?
The resolution was definitely a big challenge. Since exploration was a big part of it, landmarks needed to fit while also leaving enough space for the puzzles. And some multiple screen puzzles needed a lot of reworks to connect in the right place while still being in a space you could understand. It's still far from perfect, but that was a fun challenge.

Also the game is kinda menus and text heavy, at least for me, and fitting text in such a small screen while still having usable UI was really hard.

What did you learn?
That's the first time I made a non linear puzzle game, so I learned a lot! Especially with checkpoints, finding and creating good spots for those was definitely one of the hardest part.
The open-ended approach also meant I had to do a lot of playtesting to see if there was alternative solutions, and sometimes, looking at a puzzle from another angle led me to discover new puzzles that fitted perfectly in that small space. I don't know if this is luck or if that's bound to happen from time to time, but this was a really interesting approach to designing puzzles!
