Should have the strafe button. Where's the sandbox mode?
But besides the strafe button, what I think this game needs is an original skill or at least something not found in DvM that people would like. Otherwise it's a really lousy and terribad imitation of DvM.
It's too easy to beat it. Hunter spam usually owns any ancient unit except the super high dmg and low hp unit, that one just use the royal guard, or the turret which a measly swordsman can own. If you fight against the humans you ought to have read the dungeon advice of the so-called triangle.
Ship should not take up more than half the screen? And it should be like at least slightly mobile to move about, or even then, the screen should be much bigger and I agree with many that lasers should not travel slower than sound.
Max all mana regeneration upgrades, max your archangel, max your hobbits and elves, max out your 4 arrows, get a good turret (optional) and then slowly and painfully snipe the end to death. When he comes out just spam hobbits, elves and archangels, wizards are optional but they can hit slightly out of the range, giving you a bit more damage, golems and dwarves die in 1 shot, don't use them and dragons die in 2 hits, so they are optional
