I actually did employ all those tactics but what kept screwing me up is when you exit the tank I think the space bar should become jump. As a standard for platformers the space bar is often the jump key and I kept firing when I meant to jump. I think maybe we could employ the left shift key for fire but I;m not sure. Either way I agree with the others, what a game! I could easily see myself paying 5-10 dollars for a game like this on steam (assuming we have many more levels). The art, the thought and gameplay are all very well polished. Also I love the tank mode and the silver corner bumpers (great concept) and how it differs from the golden corner bumpers. This game has so much potential! keep working at it!
