I get not being able to collect a perfect scale, or a shiny boar tusk. But not being able to collect a dragon fang? What, do their heads skitter off their necks like spiders?
The one problem I have with it is that the hit detection is a bit wonky. I've zapped right on top of some tanks and failed to drain their health until I moved just a little bit, at which point it actually started working. Otherwise, fun game.
I hate to be rude, but have you ever even seen a car, let alone driven one? The way they handle in reverse is ludicrous - reverse reverses the direction you steer in. If you're turning clockwise going forward, you're turning counterclockwise backwards. Right now, the controls make it hideously difficult to actually steer.
Ended up using a strategy I mentally dubbed "Hell's Kitchen" at the end - 2 magma blocks, a stick block, 2 magma blocks, one empty column, and then a repeat. It basically fried anything that flew into it, if it even made it over the first column.
Definitely would have liked an ending that explained more of what was going on. Oh, and actually making the shadow things afraid of light - it's no fun to accidentally stray away and then have them chase you into a glow just so you can die.
Fun game, but it really does get easy at times. Especially the final "hard" stage - I think that's the easiest of them all. Anyway, a couple of bugs - the cannon ranges don't extend when you upgrade them, the game doesn't keep track of lost units (so you always get 0 lost), and the game doesn't seem to keep track of money spent (got the 10,000 coins or less reward despite spending significantly more). Might want to get those fixed.
