LOVE the dialog. I hope the final game dialog is this funny. And I like how you have to throw the boomerang just right for it to hit the enemy both coming and going.
A few things:
I get the 1st enemy dialog twice. But there's no enemy the second time.
A couple times the game would just crash. It seemed to be more likely to happen if I just ran through the level as quickly as possible. It always happened in a different place, but it was always at a spot where the layout was about to jump from one to another.
I think the controls are fine except I would want spacebar for jump.
