Throughout our playthrough we found some potential issues.

#At hipshots farm's house. They could enter the house without using a key. The roof didn't disappear. We didn't go all the way in, incase the game would crash.

--SPOLIER--
#At the secret area cartman area ( http://imgur.com/zuYHDtv ). Myran(one of the players) who triggered the secret could not enter the room while the other two of us could enter. He described that he couldn't move the block once he triggered it once.

--Suggestion
The game was really nice and had a rpg-estique which was enjoyable. But it would be nice with variation of music. Maybe at least two different tracks, one that appears when you enter the portal-of-no-return or something.

Hope you are able to solve these issues! :) goodluck!

well, thank u kidchris for ur feedback, the Farm House shouldn't be able to enter, even not with a key, i will look what i can do to improve it :)

I found that several walls were not visible on the map. Especially in the lava area there are many walls that do not show up.
