This update adds a simple physics engine into the game.
When I first began designing this game I wanted to focus on performance and having an additional iteration of calculations was why it was never considered.
However, after implementing and testing the physics system, I think the sacrifice in performance was worth it.
The physics adds a new dynamic to the game which gives the player more control over situations.
Using the hero, the player can move monsters by walking into them, which can help with surviving in those time-crucial moments.
Having physics also helps alleviate the overlapping of monsters by causing them to spread out.
Misc Changes
Fixed issues with associated with increasing speed of the game and intersections of high speed projectiles.
Fixed an issue with saving and resuming a map on normal difficulty that caused the towers to not work anymore.
Redesigned the level dialog layout.
Saved games now track and respawn any dragons that were from previous waves.
