Oh, and two more details, like it was already posted, the enemies are way too easy, they should have some kind of armor, don't know, or at least some other attacks, and also the guns are too look-a-like, they should have special properties, like for example, the rocket launcher gives splash damage, the Pistol pierce shields and so on \o
It would be lovely if like a double down arrow (two S's or two Down Arrow's) pressed could "jump" one plataform down ! And btw, nice MegaMan influences on the enemies !
