The graphics are fairly impressive. My big complaint with this is that it is too difficult. I don't think I lasted any longer than before I knew how to fire! It's still a pretty interesting game. I like how there's an acid version, which I assume is harder. The music seems to be fairly suiting.
There's a fairly good variety of enemies coming at you. Some of the CGI does look a bit dated. Then again, most modern games don't use CGI anyway. It seemed like this was a unique game for you and it makes sense seeing as how you've made so many. I guess it's fine.
