I gave all of these 5/5 months ago. I don't know why they got badges but they're fun and I thought it was really cool that someone decided to explain all the core concepts that go into a game.
Well, I finally decided to go for the "Coin Collector" badge and I have to say that most of the coins weren't very well "hidden" though about 4 of them were potentially a little tough.
OMFG! That third boss is soooo not fair. I beat him finally but between barrages of tracking missiles and that damn laser it's almost impossible to not die much less get through! AND it'll hit you with the laser when there are missiles incoming and knock you all the way back and off the platform! PLUS it used the damn laser on me over 9 times in a row! No missiles in between! I changed my rating to a 3/5 earlier but I'm thinking about making it 1/5 because of that boss.
This would have gotten 4/5, but because of the recoil I give it 3/5. It would be very cool if I didn't have to take my shots so carefully while being swarmed.
I'll give it 3/5. It's a fun, original concept but there's just something wrong about TRYING to complete the seven deadly sins in as little time possible.
