Update Changelog (Demo 1.5)

Hello again!! I've been working on level 2 and i fixed some of the bugs that I and others found

• Fixed a misspelling at the beginning of the game
• Fixed some weird looking spikes in the "Chocolate Chip Cookies" Challenge
• Removed some debug features that were still in-game
• Fixed the skeletons' bones appearing at the spawn instead of their death's position
• Fixed Misplaced attack hitbox when you're attacking vertically
• Fixed a glitch that lets you collect pages inside the challenges, locking them out of your current save file

Thank you guys for the support!!!
