The puzzles make sense without any interface descriptions or guidance, allowing players to immerse themselves in them. I enjoyed the mask system and effects, it's a cool idea and is used impactfully. The character model and icons are a good balance of being functional but mysterious and have some nice reactions. The movement arrow may benefit from showing the direction on the map you are moving, since clicking at the bottom of the screen usually means going to the previous room instead of south on the map, which can be confusing.
The sound design is good, with clips for various actions. This is the type of game that works well with environmental audio instead of music and you have made great use of it!
There's a large assortment of environmental and character art, adding an ever-present feeling of exploration and discovery to the adventure. The transformation scenes are all interesting and fun to find. Some like the frogs and jailer could benefit from moving a bit out of the way after being solved.
The game feels both expansive and fully complete, which is always a big achievement for a jam project! Alternative routes through the maze could be added as a bonus, but nothing in the game feels unfinished. Very nicely done!
