bubble cat

welcome back, bubble cat. we have another situation, and this time you've only got 60 seconds

> how to play:

• arrow keys: move
• X/Z: continue to next level
• ctrl-r: restart
• ctrl-m: mute

you don't have to full-clear every level -- skipping a level without clearing it just gives you a points penalty (-5 per remaining bubble)

> code:

this game was made to fit inside two tweets; i.e. <560 characters of code. here's the full game, in 552 characters: (and no external sprites/sounds)

> some code highlights:

• convert btnp() bitfield into movement: b=btnp()if(b>0)s=b*.6&.75if(r)x+=cos(r)y+=sin(r)
• buffered input: if(not r)r,s=s
• out-of-bounds check: w=x\7+y\7~=0
• animated score display: d=sgn(n-m) if(n~=m)m+=d
• collision checking: if(y*7+x-x\7==i)
• draw player: ?"★⁵8d🐱",x*9+1,y*9+3,7
• animated score floaters: for a in all(o)do a[3]-=1?unpack(a) end
