Updated build can be accessed here:
A couple of notable updates
1. New enemies
2. New terrain elements
3. Gravity and Physics modifying zones
4. Some map UI updates
5. New mission objective (Search and Destroy)
Be sure to check the map for your objectives. Also, ryanrybot, I fixed that bug you pointed out!
Thanks everyone for all the encouraging feedback! Getting to a point where I can start fleshing out some of the other aspects of the game (the level select screen, title screen, mission summary / ranking).
