the last airplane beat the purpose cause you going to have won the game before able to buy it (without senseless not-needed grinding) and things feel too easy especially for the bossess-- the bossess superiority is just its amount of health, they dont even have adequate fire power. But what most disappoint me is minigun sfx which give me headache (auto fire) because it is too loud.
actually the developer doesn't even know the existance of motherload before he got some betatest feedbacks. It show how great developers sometimes bump into same great concepts. This also far more friendly to play than motherload.
I like it but it need to reduce the amount of controls, make some sort of pause before the actual game start (because I have problem switching between tablet with keyboard), and well.. better artworks or at least design.
