1. yea its kinda rough but i will make better platformers from now on i just quickly added all of theese parameters and didnt think much of it
2. yea that too, weak parameters. getting the hang of it tho
3. i tried to fix it but i kinda failed i guess
4. yea that was kinda dumb but i didnt know what to do so i just made the jump force higher, yea i should have lowered the gravity too
5. i dont understand xD
