I like the concept, but you might have trouble with the click-to-move thing if you decide to add weapons, items, or doors... or really anything that would need to be clicked on.
Concept is great, and execution is pretty good for a first try! Big problems are the learning curve (practically non-existent) and upgrades. I first used by blue bomb thingy on level 4, and it didn't recharge again until level 6.
