Mashy
The game looks cute and has a fun style to it appearance, but it suffers due to a lot of other factors. Hit detection is by far the worst, often times finding myself spraying ammo that merely hits the wall behind a guy when it should be going through their head. Secondly, and probably the worst is that there is no automatic fire function on the gun. If your game has you killing hoards of foes that take several bullets each then he should be shooting bullets with merely holding the button down without having to press it each and every time you shoot.
Lastly the first level was just freaking dull. You don't get a teammate, the boss is a giant wall(And it does nothing) and the hoards of the same generic enemy provide no challenge at all as all they can do is shoot straight ahead. While the game is inconsistent with being able to shoot through some platforms but not others, it's still a breeze to just take higher ground and kill till you beat them all.
If you fix all the bugs and let the team system get implemented first level, it might be worth a solid playthrough, but I found myself so bored by the start of level 2 i didn't care to play anymore.
