I keep dying because the ground is slippery. This wouldn't be so bad, but I have to go back through those unnecessarily hard-to-jump-through pipes again and again and again and again and again and again and again and again and....
I was going to make a sarcastic comment about how there aren't enough self-advertising money grabbing things, but I couldn't think of an example that you haven't already done.
I have a infinitely tall tower, and my enemies have a small ship? Seems fair. I can pretty much hit everytime, anyways. Might want to make it a bit harder. It's slow, but thankfully short. Well, just keep learning. You may get there one day.
Pretty good, but sometimes due to the speed that a sharp turn can show up, it can lead to, near-impossible or even impossible situations. I would recommend moving the ring back or making the screen wider or something.
Kinda wish you could keep the inventory out instead of having to keep hovering... Also kinda want it in the bottom left corner, but that's just probably from playing Fantasy Online too much :P
