Luckily it seems to only have the one level, because if it had more, I'd be losing years of my life to this game.
http://nagoya.cool.ne.jp/o_mega/product.htmlThe controls are simple: Z to suicide and arrow keys to control your ship.
The goal is simple: suicide and blow up some flying blocks when you die.
The gimmick is simple: when you blow up blocks, they blow up, and there's a chain reaction. Good chain reactions get you bonus lives (bombs) and extra time.
Odd colored blocks (pink and grey, as opposed to white) contain powerups, usually time or speed. Getting killed instead of suiciding gives you a time penalty.
Oh, and you'll need something to open LZH files. WinRAR will do.
