Finished within about 15mins. Overall a cute and fun game; I'm especially a fan of the character designs (translated to pixel art) and animation. They're simple and charming and beautifully executed. I would love to play more Gunnerkrigg Court mini games like this, but I also recognize these games take a TON of time to create.
As for the game mechanics, I wasn't a fan of climbing ladders. The moment you lifted your finger from the up-button, your character immediately lets go of the ladder and falls. This made pausing to look around or even getting onto another platform tricky. This only became frustrating when you'd fall down one ladder and while trying to panic-click your way back up you fall down 3 more ladders or platforms and find yourself at the bottom of the game.
When you're tasked to Find Mort, it's rewarding to see Mort's cute animation and big smile waiting for you... but then becomes super unsatisfying when you get in Mort's hit-box and there isn't a transition from Mort to Lv. 2. It feels like a glitch, even though I know it isn't.
Lastly, I want to go through every single door! Not just because they're doors, but because this is GUNNERKRIGG COURT! This is more of a me-problem than anything else, but boy did I waste some time trying to open those doors. :P
To be expected, for a new game being made by a new game-maker. :-) And yes, the music is delightful. Some players might like to turn the sound off; myself, I'm enjoying it while typing this reply. The ladder issue is because the programmer simply forgot (or didn't consider this) to have a game designed for users to pause and look around while on a ladder.
