Weekly Update #40 - Cardboard Crown

Hey everyone! This update contains a lot of awesome stuff! However, the tiles are currently undergoing a rework, so the game looks very bad. Oops! I hope you can deal with it until the tiles are finished.

• Added co-op! This update might've been the worst time to add co-op, but hey, at least it exists! You can access it from the menu. Currently, both players must play as the same character, but this will be changed in the future.
• Added a new passive item: Cardboard Crown.
• Reworked tiles to add tile depth and the ability for water and other liquids to go under walls. This is still a process, so bear with us.
• Rock no longer drops and can only be found the alternative way. Increased that chance from 0.5% to 1%.
• Added dud bombs. Bombs have a 1% chance to dud. Dud bombs can be picked up and used as a weapon.
• Added visual bullet prediction to Pool Cue.
• Scrapping passives now gives 10 Sol instead of 5. Empty Can increases this number by 10 Sol instead of 5.
• Added an open alpha disclaimer to the main menu.
• Added two new weather events: Fog and Rainbow.
• Added a loading screen for going in and out of houses.
• Added special visuals for Airsoft Gun, so that it's more clear when you cannot kill the enemy. Increased Airsoft Gun's knockback.
• Touched up the Sundae sprite.
• Renamed Extra Arm to Biceps and changed the cryptic description.
• Everything uses a system I implemented called precision movement! Now all player/enemy movement works the same way.
• This means tile bounding boxes are more accurate. No more inconsistent tile collision.
• Campfires hurt enemies and you properly now.
• Cactus objects don't hurt you anymore because they can only spawn on walls.
• Xandra Pounce now properly calculates the acceleration change, so horizontal and vertical pounces are just as long as diagonal pounces.
