I liked the artstyle, even though it was a little inconsistent, the dialog was fun and puzzles themselfs, especially the one with the banners!
Gameplay could improve but I thought it wasn't bad at all, having no pause or way of restarting other than refreshing the page and going through the whole starting section again was a bit of a pain and I did notice some less polished places on the sprite ordering as someone has already mentioned.
But all in all it was a fun one, really did like it, so much so that i retried a bunch of times until I could get out of the spikes room and went back to the starting area (i assumed that was the end). Good job tho!
