Visually, game looks amazing (as for 1992). Beautiful backgrounds and cool enemy designs! The difficulty level is high, enemies attack in an unstoppable wave, sometimes you almost have no chance to avoid hit. Collecting coins is dangerous and you lose them when taking damage. The worst enemy is the time limit. Surprisely, boss fights are easier than regular levels. May rating is 4 stars (5 for graphics, 3 for gameplay)
