I liked the simple graphics, especially the main character, which is really nicely sprited and animated. Gameplay is really simple, and too repetitive. Quite easy too, maybe too much. What disappointed me most was the lack of surprises and the dull story. The only real challenges were the bosses, but those were scripted quite well, while the upgrades were not that useful and I spent 400 points just for the last boss, to have a bit more health.
