Update 1 hotfix 2

Thank you to all the people reporting bugs and suggesting ideas in the discord and on the discussion page! It's greatly appreciated :)

And thanks to all the people that left a review, those help me out a lot!

Here are the fixes/changes:

- Decreased the amount of particles spawning when boulder tower uses seismic slam, should get rid of the lag spikes
- Fixed a couple bugs regarding the stone of attack speed and stone of damage. (this took some time, but it they should work perfect now!)
- Fixed a bug where you could level all tower abilities when having 1 tower hit level 10
- Re-balanced the waves 20-30 and 30-40 (not the boss waves!)
- Changed names to Flamethrower
- Added a timer, can be enabled in the game settings in-game (it's turned off by default!!)
- Added the ability to zoom in via - and + key, also added this to the tutorial
- Fixed the bug where you get an achievement for a boss wave while dying to it
