What's new

The 26th, content patch day.

2019-07-26

Today we pushed a patch that will add some variety to the game. This doesn't add game mechanics but it does include a few variations on environments and foes. Most of those are hidden and most of those will sneak up on you when you don't expect it. Those safe space hazards might not be always harmless. Also some re-balancing has been done on two bosses, the Neptune boss and the Saturn Boss. Finally some bug fixes have been pushed, the dreaded super powerful explosion should be a thing of the past. This is the first content addition. This will not be the only one. Enjoy!

One of the most satisfying aspects is landing a perfect shot on an enemy ship's cockpit, disposing of them quickly. The premise is quite hilarious, although you can, and should,...
