Once you're fully upgraded, just strafe across the screen slowly (by casually toggling the arrow keys on/off) about 1/3rd from the bottom. Doing so keeps the enemies cleared, and the missiles are always headed where you were about 2 seconds ago. You may still take a hit here or there, but you'll also get the heals. It's just a matter of patience then...which I haven't, since I'm actually interested in /enjoying/ the game.
Games like this one are often a pain and mostly tedious click-searching and trying random crap. But this one actually made sense--the things I had to do were actually the things I expected to have to do. It is annoying when items which should obviously combine don't, and then you find out later after floundering around for a while that now they do. But other than that it's much better done than most of the other click-puzzles on Kongregate, and more interesting/fun besides.
I can jump 3 times and bounce bullets all over the place. Great. Now if only I could jump or shoot within 30 meters of corners without getting blocked. ...and switch weapons without moving my hands to the other end of the keyboard.
It would be a much more interesting prospect if the maps were far larger and one had to traverse a great distance facing increasingly more dense collections of creep spawns as one made forward progress (while keeping the earlier ones at bay for the sake of resources).
As with almost every unity player game, I have no invert mouse and the tiniest mouse movement produces dozens of full turns. Plus the pointer needs to be bound inside the game area. Otherwise, you just keep clicking outside the game and losing focus.
Why can't I just click and drag to make a selection? What on earth requires slow loading screens on such a simple game? Where did you get your "facts?" And why on earth would I want to "brag" my score?
I keep dying because in mouse mode I try to input the key commands as directed to escape disaster, instead of clicking the images. Why can't I just use either?
