To trigger crash with sprite id: -1

[MasterNama17083]

Hello. I've got idea let's see how did crash TIC-80?
https://user-images.githubusercontent.com/80534869/136331051-310e86d7-5bcd-4aff-b6ad-244713fadba7.mp4

Code:

t=0
x=96
y=24

function TIC()

	if btn(0) then y=y-1 end
	if btn(1) then y=y+1 end
	if btn(2) then x=x-1 end
	if btn(3) then x=x+1 end
	-- to trigger crash
        if btnp(4) then spr(-1)end
 
	cls(13)
	spr(1+t%60//30*2,x,y,14,3,0,0,2,2)
	print("Press A to trigger Crash",54,84)
	t=t+1
end

How it works?
