Using the W and top arrow key to jump is likely going to add soon in a later update thing, because a lot of my friends are also saying that, and the only reason I didn't do that is because the bow can shoot up, and the originally the game would have started with both the "archer" and the "knight" would have had their bow and sword in the beginning, but when I simplmyed the game down I forgot to remove that :P
and also with getting separated, did you use the yellow teleport spots?
thank you for the feedback :)
