I've gotta say, I loved the bossfight and I loved endless mode! But something felt lacking in the normal levels, and I think I've pinpointed the reason why: they don't encourage the use of the platform as a weapon. It's very, very difficult to hit something while you are still moving to the right, so you have to stop to kill - but the goal is towards the right, so it's much more efficient just to dodge enemies rather than defeat them. This problem was amplified in the level before the boss, where new enemies would almost instantly replace the ones that you offed. Landing a hit and managing to catch your fall is the best part of the game! That's why I found the other parts of the game much more enjoyable - progress isn't distance-based, so you can stop to prepare shots when necessary.
