Absolutely unplayable under Linux. The tutorial doesn't work...

@skill34 : To complete all side missions, you have to complete the "boss run" too. This side mission is unlocked when you complete the last story mission.

Hopefully, there's only two levels. This game was driving me crazy, mainly because poor control sensitivity (sometimes moving a lot, sometimes not moving at all...). Not worth a buy.

Since 1.3, the ship doesn't fire anymore after a while ... can't play to this game anymore.

It DOES save games, but you MUST NOT go into "Unlocks" once you have unlocked the 3rd lock : it makes your savefile unusable, at least with Firefox on Ubuntu. Starting again for the third time. For this bug, 3/5.

There IS a pause button : just look at the upper right corner ;-)
