I managed to get into this. Granted, that was just because I wanted to get that medal! It got frustrating like that. Those red guys are the worst. I admit the details aren't that good. It's still quite a playable game.
It's weird how I just zipped through the first two levels. There were certainly a wide variety of enemies here. It was hard with how they all had different attack patterns. I never heard of this pixel thing for this year.
