v0.1.9 - Performance hotfix

Tower Survivors

Fight an endless horde of evil minions and survive as long as you can. Collect loot and purchase new upgrades and magic abilities. Summon allies to stand along side you and survive the horde!

This update should fix the late-game performance issues when flames begin to spread. I had some underlying problems in my physics layer that were causing the engine to detect collisions in a very sub-optimal way, so when all those fire elements are on the screen checking for spread, it was making quite a mess. I've refactored the physics layer completely, so you may notice some things move a little differently than before, and some things are a different speed than they were before. I'll be tweaking this moving forward to try to get back to the balance I'd found in the last patch, but for now I wanted to get this out so that everyone can enjoy the end-game without a supercomputer!
