1280 x 1024 Screenshot:
http://boundlesssupremacy.com/Cappy/aquaria/Screenshot.pngAquaria works perfectly on wine 0.9.52 (currently newest)! I had to set my resolution in init.cfg to 1280 x 1024. to get it to work perfectly. This caused my ubuntu's (Ubuntu Gutsy 64-bit) top and bottom panels to show up above the game. I fixed this by adding the arrows on the sides of the panels and sliding them away when I launch the game.
I don't get any lockups or crashes in the game =) The only problem I have is that the game crashes if I minimize it. I tried running the game in a separate X (to be able to "minimize" without crashing) but I haven't been successful with that so far due to my nvidia settings not wanting to launch a new X session. Possibly a Gutsy compiz-fusion problem - will look into it later.
I completed the demo and found all the hidden treasures (except the ones kept from me by strong currents). Will definitely buy this game! $30 is a bit expensive imo but one of the very few games I can say "worth it!".
Perhaps aquaria should be released for linux and wrapped in wine seeing as how well it works! =)
Other notes:
Game did not work well on wine 0.9.46 (default ubuntu universe install; not the winehq install):
Could not save progress - gave black save bars and could not see cursor.
When targetting a creature in energy form the cursor would completely disappear when it locked on to a creature.
Was also able to get aquaria into full screen by changing my desktop resolution to 1024x768 and using game resolution 1024x768.
If I was using resolution 1280x1024 and used a smaller game resolution when I quit the game my desktop would become the game resolution.
