Thanks for the feedback! You basically hit the nail on the head for what I feel I could have improved on as well. I originally planned to include a brief tutorial which layed out the controls in the first level, but I ran out of time before I could implement it. And the physics certainly need a lot of tweaking, so I'm glad people are informing me of issues I didn't previously see. I'm glad you like the idea; I'll be sure to check your submission out too!
