Thanks for checking it out Alixxir! Yeah we took on too much and couldn't iron out enough bugs in time.
Items should be droppable with E but it's super unreliable and doesn't often work, haha. The controls should also be in the options menu in-game. :)
I'm really glad you had some fun with it though - hopefully if we find time I'd love to add in a tutorial that we had no time to implement because I think it sorely needs some explaination.
