Event #9 - I don't understand why are you comparing the coins variable with the coins1 text. That condition will never be true, because events #3, 4, 21 and 22 set the text to the variable on every tick - they will always be equal.
Remove sub-events 9 and 10, your event 8 should look like this:
saveGame On clicked: LocalStorage set item "ex_coins" to coins
Also, events 4 and 22 are saving the game on every tick - saving so often is a bad idea, don't do this.
