This was pretty fun. At first I wasn't sure what was going on as my cursor was off the screen and it wasn't shooting. Then I moved the cursor onto the screen and was able to defend myself. I did end up falling off the last platform but didn't die. Couldn't shoot or do anything other than watch the time run out. Really all I can offer is to add a few more enemies. Maybe ones that force you to move around a bit more and then making you use those controls. Otherwise I did just as well standing dead still shooting, really no point to move around otherwise. Good job!
