Spellcasting update & increased potion drop rates on 1/23/19 — Arcane Domains Steam update #788240

The following changes were made to the game: Killing an enemy drops a potion 70% of the time, rather than 50% of the time. If an enemy drops a potion, it appears twice as fast. Breaking a crate open drops a potion 75% of the time, rather than 60% of the time. There has been an issue where if forward is held at the time time as both mouse buttons, the player cannot cast a spell. this has been fixed. The magic walls that appear when the player reaches level boundary are less bright, and less jarring for some player's eyes. Minor changes to crate, treasure, & enemy placement on a few of the levels.
