I remember when I used to go on Armor Games. These games, as simple as they were, were some of the better games on that site.
Over the years, I kept thinking, "If jmtb02 would package up his games and sell them, I think I would actually drop money on that!"
And I did! It was within a week of discovering them!
Some of his earlier games were hard for the wrong reasons, but the music and the way they are presented are the hooks.
After downloading this collection, I've only played for five minutes, but I am not bothered about leaving a glowing review. Just know that you might be stuck for a bit if you don't have great coordination or reflexes.
Oh, and my five star rating? I'll admit, I'm biased by nostalgia. Just get through the tougher parts. These games do become less aggravating.
