I really thank you for the feedback. The Visuals are indeet something, that seems to be one of the things i can do nicely so it is nice to read the compliment for that :)
The colliders will be my grave one day, it was the first time i was trying to do a platformer/Metroidvania inspired Game. I was planning to work on this further after the Jam-step by step but was thinking that i will make only a polished prologue out of this and switching to Twine for the Story and the important visuals, because the watercolor/aquarell is taking a lot of time and memoryspace. It is a difficult decision.
