Because Linux makes you sexy.
yea right

but it does look rather sexy, does it not? yea.. KDE + Compiz-Fusion can look pretty

and it doesn't slow the game down at all in Wine! Framebuffer Effects enabled and everything.
Still, I wish it was a native game. Wine is still.. you know.. Wine...
Anyway. The game is too much fun to let it be, and now that I've played the demo I can't stop playing.
1. It runs fine in Wine, so there's not really a reason to not buy it for my Linux laptop, unless some eerie Wine bug pops up in the middle of the game

but let's hope that doesn't happen

2. But even if something wouldn't work.. This game will actually make me borrow my mum's Win XP laptop to continue playing the game

I'm a big fan of the hand-drawn graphics by Derek now, and a huuuge fan of the musical talent that Alec possesses, even more than his programming skills actually, even though they are also top-notch.
For me, this game is really something that makes you rethink the important aspects of gaming. The fact that it has been developed by such a small company amazes me. You guys really deserve some time off for now. I really hope Aquaria becomes a success for you guys.
Oh, and.. now that you have gone through all this... I mean.. the porting stuff... maybe you could - pretty please - consider to develop the next game as cross-platform as possible from the start?

Like watch your casing, test it frequently, and use a cross-platform library for sound

I mean.. I would understand if you wouldn't want to port this game to Linux anymore because of all the extra trouble, and because Wine seems to handle it well enough.. but maybe, for your next game....? I sure hope there will be a next game! I'll be expecting one in the next 5 years

Preferably one that actually works natively on Linux.. hehe..
Anywaaay.. Good job with Aquaria. You can actually see that the game has a polish to it that you only see in games that have been developed with great passion. Kudos to Bit-Blot.
