1.5.3 changes:

-Added fast forward button. Press F to toggle. Will deactivate if you move or take damage. This raises the framerate so your mileage may vary depending on how good your computer is and how many enemies there are but I'm sure the majority of computers can handle this for the early nights which is what this feature is intended for. Might set the framerate to a weird value if you don't have a 60HZ monitor and VSYNC is on, so I recommend turning it off.

-Enemy health scaling now ramps up linearly from 1x base value to 1.5x base value on Night 11 on Hardcore mode, instead of being fixed at 1.5x like it was previously. This should give a bit more leeway on Hardcore for the initial setup of your base. Nights 11 and beyond are identical to previous versions.

-Material box spawns per night on Hardcore mode increased by 2

-Mine damage 900 > 999

-Super Sentry Gun cost increase 500 > 400

-AOEs are now slightly more lenient instead of only calculating if the midpoint of each enemy is inside the circle.

Last update for a while probably unless I break something and need to hotfix it.
