Well, here's my run-through:
-There's a quick-step in the walking animation
-The animations don't follow to the top screen. The animation becomes 'standing still and looking right', even if he was looking left and jumping
-Collision errors, but I think you don't really want to hear about those?
-If you manage to get to the end while looking left, you end up off the screen. The screen scrolls back to the beginning
-If you stop running, and then start running again, you go for about a second before the sliding view picks up and catches up to you. It's so small that it feels like a jerk instead of a pan
-The panning is too slow. You can travel half the map before it catches up to your side. Taking out that slow decelleration should help, too
-Enemies that randomly touch your lower half will die. This should be aimed at the feet, rather than just 'anywhere low'
For the purposes of alpha/beta testers, would it be possible to add a function that resets all the enemies? (By pressing the start button, for example)
Am I helping? I won't bother if I'm just telling you things you already know.
