Vaesea's Platformer Base (Main) v1.0.0-beta.1

This is the first beta release of the main branch of Vaesea's Platformer Base!

Linux build will be uploaded later.

Make sure you read the README.md!

Features that will be added later are:

• Credits Menu (Since I've already made the tag, I can't add this to beta 1 now) (v1.0.0-beta.2)
• Ducking / Crouching (v1.0.0)
• Skidding (v1.0.0)
• Replacement of Solid Object Layer with FlxTilemap's setTileProperties (Not exactly a feature but an improvement instead) (v1.0.0-beta.2)

Features that still need to be decided:

• Echo-Flixel support? (Reason for: Slopes) (Reason against: Slow)
• FlxTilemapExt instead of FlxTilemap for state.map (Reasons for: Slopes, Solid Object Layer will be replaced with FlxTilemap anyways) (Reason against: Seems a little complicated)
