Did the dev even test these controls? They are pretty bad no matter how you look at them. I have tried playing this game both left and right handed and it doesn't make it any less clunky. This just sort of plays like an old flash game.
Sound can randomly cut out after a death. This wouldn't be a problem if there were skippable into screens for the reloads. Also, does the quality button do anything?
This game is like the ninja warrior of platformers: Totally impossible but SOMEHOW you are expected to do it, again and again.
Great but seriously, screw that yellow bird
So I don't know if this is intentional or not but if you put one of your units (any) over the enemy's war factory, they can't make anything. If it's an air unit they basically don't even try to kill it
