Engine might be almost completed

I'm not entirely sure, but I think I've added most of the stuff I want to have in my engine now, and I think there's just optimization, enemies and some interface I will have to add now before I consider the engine done. I have kind of started a game even though my focus has been the engine, but I'm not entirely sure were I'm going with it yet. The idea is a fast paced, unforgiving, sci-fi sidescrolling shooter, kind of in the style of Hotline:Miami. The horror game has kind of been pushed back, because I'm having so much fun making a more fast paced game, but its still in my list of to-do stuff

These are the updates I remember since the last update (I've done a lot, but I don't think I remember all):
-Light engine
-Portal gun
-Customizable buttons for interface
-Customizable sliders for interface
-Light editor
-Pause menu
-Bullets that kill you
-Jetpack
-New textures
-Support for animation
-Textboxes
-Text editor (something that takes a lot more work to add than it should take!)
-Saving and loading of maps in-game
-Some small changes for particles
-Bug fixes
-Some minor optimizations

And here's a video showing the light engine, and some other features, but mostly the light engine:
