Avoid Posidon's Wrath Interface Needs Work
I like the concept and think it's a great idea. But... The controls are awkward. The use of "UP" key to jump is too unintuitive. Also, the need to click three time with mouse then quickly switch to keyboard JIT to die is annoying.
Suggestions:
Use Space Bar for Jump.
Add a pause before action, (Look at Street Fighter 2's Example. "Ready ... Fight!!")
I look forward to seeing the next version.
