Good, but easy
I'm afraid this was pretty easy. I never took more than two hits on a level, and I only let one enemy slip past me during the whole game. My final score was over 150000.
Anyway, the witch was cute instead of hag-like, and the 3D enemies with smoke looked pretty cool. The thing that threw me for a loop though was how the green and red enemies emitted grey smoke like everything else. I think it would be better if their smoke had greenish and redish hues, repectivly.
Now for the boss. I liked how the boss used visual cues before his attack, to let you know how to dodge. However, the fact that he simply used bigger versions of the same, easy-to-dodge attacks all game lost points with me. However, I appreciate that my attacks do not simply hit the bosses arm, but rather they keep going until the hit its chest.
So to put it in a nutshell, it was good, could use some improvements, and this gets an 8/10, 4/5. Hope the next one is even better =)
