All you can do is move around and shoot the creatures. I put in a debug mode just click CTRL+C to enter and CTRL+X to leave.
I am also working on versioning; it is not version 1.0, I just put this up there to get some feedback on the animation and progress. I am using the creatures and explosion from the tutorial (I will replace them when I create the images). I am still learning this as well as developing. I come from a programming background in C++ and C#. I actually have an engine I'm working on using DirextX for 2D but I find this MUCH MUCH easier to use. I have already come across several limitations of this engine but since it is also a WIP I have no complaints, enjoy! :)
Quick Edits & Fixes (until I get my bug tracker and forums working):
-Fixed movement (can now move up and down in debug mode, just no animations yet)
-Fixed debug text
-Cast animation speed increased
-Added Magic Missle spell cast with right click
