I'm glad.
The final output was so different from my original idea I had no idea if it was any good. The original idea was more like snooker crossed with a tower defence where you could build the angles to bounce against and knock the enemies into each other to chain damage etc. But it turned out to be less fun that it sounds and difficult to implement. I also, thought at some point it would be fun to do something like kirby tilt 'n' tumble. But it felt too rip offy.
