New 0.28 update. This update is an incremental update that improves several parts of the "core" gameplay.

Plasma rifle Sights

The plasma rifle now has a sight. This sight fully works stereo, and its highly accurate. If you can see that sight, the shot will go there.

HEADSHOTS

Enemies now receive 50% more damage if you headshot them. This is for all the basic enemies, but not bosses.

Mage Enemy

We have a new enemy type. The "mage". This enemy will appear on the harder difficulty modes, and he glides around the map, teleporting around too. Be very careful, because he can throw magic at you and that magic will follow you even after you dash. Shoot it to explode it mid-air. He has a lot more HP than normal enemies. Some of his animations might be buggy, If you find him doing weird stuff please report it on the forums.

Achievements

Basic achievement support is now here. This first stage only has "completion" achievements. One for easy, one for medium, one for hard, and one for Extreme. More achievements are on the way.

Extreme mode

A new tier of difficulty has been added. This is the Extreme mode. Extreme mode takes the difficulty of the hardest of waves on the Hard mode, and makes it even more. In Extreme mode you only have 1 extra life, so if you die twice its over. Enemies are faster and deal more damage, and there are lots of them. It uses the same weapons as the Hard mode.
