bubble cat (itch)

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 and no sprites! here's the full code:

x=3y=3o={}m=0n=0p=circfill::_::z={}for j=1,13do z[j]=rnd(49)\1end?"⁶!5f2cC" while t()<60do?"⁶1⁶c" b=btnp()q=b>8and"⁷fdc"d=sgn(n-m)u=x if(n~=m)m+=d d+=6 p(32,32,60-t(),1)v=y?"⁶w⁶t"..m,24,27,4+d if(b%16>0)s=b*.5938&.75 if(not r)r,s=s if(r)x+=cos(r)y+=sin(r) w=x\7+y\7~=0 for j=#z,1,-1do i=z[j]d=q and"-5"b=i\7*9a=i%7*9p(a+4,b+4,3,j|8) if(y*7+x-x\7==i)w=del(z,i)d="+1"?"⁷d" if(#z<1)d="+10"q="⁷egc4" if(d)add(o,{d,a,b,d*11})n+=d end?"★⁵8d🐱",x*9+1,y*9+3,7 if(w)x,y,r=u,v for a in all(o)do a[3]-=1?unpack(a) end?q or"" if(q)goto _ end?"⁷dafa" ::e::goto e

(that's only 548 characters, but some of them (like the cat face) cost two characters on twitter)

> some code highlights:

• convert btnp() bitfield into movement: b=btnp()if(b>0)s=b*.5938&.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

thanks for playing!
