I managed in about 40 minutes, it was just one jump that gave me grief, it was pretty frustrating at times (I missed the last damn jump) but overall I did have some fun with it. I will say the engine is not great for precise platforming.

My biggest problem is the hitboxes which make me think I missed when in actually I made the jump, my damn feet are standing on thin air! Its very disorienting.

Its also easier to do if you have a buddy to chat with on voip who gets to suffer with you.
