I wasn't able to beat the game so far, but I wanted to keep my promise and review it before the jam ends.
Visually, your game looks good — it doesn't quite look like a Game Boy game, with the message boxes having a higher resolution than the rest of the game world, but the pixel art and environments look good and convey a decent amount of detail despite the low resolution. The lack of any sound is normally something I'd give 1 star for, but considering the game's focus on its environment and puzzle solving, a background music track would probably just be distracting, and the sound of your main character's footsteps works well for the game's needs. However, my main problem with the game is its difficulty curve — two of the puzzles in the first set are quite easy, but the one to the left of where you start is quite challenging, and stonewalled me until someone else got the solution. I also didn't like that you have to start the game over every time you open it — the title screen gives you the option to load a save, but you're never able to in the game itself.
