The gameplay is well done, along with the animations, but needs to be updated, and why you cannot shot? would be nice.
The graphics (excluding megaman) are pretty basic: Green Hill, Floating Plataforms..... you can make better things erasing the mainstream concept and starting another from scratch.
Is not for sound like a Douchebag, but please, avoid the publishing of unfinished content like this.
I give you 1.5/5.
