It's an awesome vertical scroll-shoooter. A lot of weapon types (both front, rear and sides), generators, shields, ships (SUPER-CARROT!!!), several different planets with their own climates, giant swarms of enemies...
...and familiar sound, when you pick up secretlevel-item ^^' Great work, Eclipse Productions!
But this game became too easy for me since I can complete all 4 episodes on Impossible-difficulty. Anyway, I replay it from time to time...
P.S. Sorry for bad language.
P.P.S. And I still cannot beat first level on Suicide-difficulty.
yayaya it's great game. I got through like few or several times back then!

Surprisingly! I wish to play in it in this game.
There could be a problem when you try to launch the game under Windows.
http://code.google.com/p/opentyrian/ - there you can download the port for this game that solves this problem
I also like this game alot. Too bad the open source port is actually worse than just running everything in DosBox...
