About Bio Senshi Dan: Increaser to no Tatakai

"Bio Senshi Dan" plays a bit like the original Castlevania game, but is more non-linear at times and its in a futuristic setting. You travel back in time to stop some kind of bio-mutations before they become too strong in the future. The game is a mixed-bag. Graphics and sound are surprisingly well done, but the controls and especially the fighting is not much fun. Enemies are sometimes hard to hit, and there is once again a much too drastic knockback effect to your character when he is hit. Overall an average game, which doesn't look too bad when compared to similar games on the NES in 1987.
