awesome day 21 update

(just found this cool draft from like 7 days ago about that update i made like 7 days ago so i guess i'm putting the changelog up now my bad)

hey i did another update to fix whatever came up over the past few weeks

• Centered file delete text so it doesn't cut off sometimes
• Changed a sprite of a spike in 5-21
• Made a cool gun solid in 5-25
• Fixed walls at some end levels hopefully actually this time
• removed a block (one) in 7-4
• Made some lvl 8 end sound effects better (they looped all weird)
• Added a few if statements for fun

this will probably be the last update unless i find something too big to ignore but who knows maybe ill release 5 updates in a row that all add nothing and just lie about the contents of each. ok bye
