Wow, you packed in a lot of gameplay for a week! Doing everything yourself as well, pretty impressive. Was quite enjoyable, very cohesive, fit the theme, decent platforming, list goes on.
It's no big deal but I think I may of found a bug? It's unrelated to the one on the Jam Page. One of the walls near the lake has no collision, can get underwater and out of bounds. At first I thought I found a secret passage but it seems unintended? Didn't let that effect rating though.
All in all very good entry! Great work!
