Overtime Overhaul

So my game is getting analyzed by Game Dev Topics tomorrow morning. I've had an idea for how to improve my Overtime mode for a couple days so I really pushed myself overnight to get todays patch out, and while testing it this morning I really had a "This is the magic" moment. 

The basic issue with Overtime was that the enemies are just scaling linearly and the player is almost certainly done levelling up, I do want to add extra enemies and spice to that mode so that is definitely a plan for the future, but that's a lot of work too. I realized a big part of the problem is that a large part of the fun in the game is the decision making process while levelling up, choosing your weapons and items etc. So what I have done is extend that philosophy into the Overtime mode, but now instead of the enemies scaling linearly with time it is now a combination of global enemy upgrades and player chosen enemy upgrades.

At the start of Overtime and every 30 seconds after a menu will pop, one of the 4 following mutators will be applied

1. Enemy Health Increase
2. Enemy Speed Increase
3. Enemy Damage Increase
4. Enemy Spawns Increase

Additionally, the player will be offered 3 options out of the following 9

1. Alien Shooter +1 spawn
2. Periodic Damage, Ignores Bubble
3. Your Max Health Reduced
4. Your Healing Reduced
5. Your Movement Reduced
6. Enemy Health Increased
7. Enemy Speed Increased
8. Enemy Damage Increased
9. This Menu Appears Faster

This keeps the pace of constant decisions flowing and although I may be biased it seems like a fantastic addition to the game and I think is the start of the spice I need to really make this game special.
