Got the game now. I've been playing it for a while. It's really fun! I've been able to raise my level to 50, and almost collected all the devil cards. I missed one that you can only get ONCE in a challenge game, and won't appear after. I didn't realize this until after I played through the levels again.
The only other I'm missing now is Mr. Angel from the last world. I know where this one is, and is not a rare card. It's just really hard to get due to its area location. It's one of those where you have to beat the devil to get it. This one is on top of a small angled pillar in a pit filled room of platforms. Every time I hit it, approach it, or shoot a projectile at it, it either falls off, or flies away. Not to mention the other buggers also get in my way.
But other than that, it's been a really fun game. I have not made any serious creatures with it. Though I have been wanting to try to make GIR (robot form) from Invader Zim since he would probably be easiest to draw. Next I would want to try making Pulse Man. Maybe making a MegaMan would come later. I've seen a few classic series megaman characters, but nothing really that decent. Only one that looked good was the two Zeros, MegaMan X, and Mario all made by Japanese players.
My main attempt will probably be PulseMan, after I can actually draw something. Though I'll probably try making GIR before though.
Some of the cards actually gave me a laugh. Esp. the Taito logo card. That one got me laughing. Others like the flat, 2D invaders, and Bubblum/Bobblum I thought were really cute. ^_^
