still thinking about the common lisp tamagotchi

apart from the simple common mini games of up-down, higher-lower, left-right, i want to include a little shop where you can buy foodstuffs and reskin your virtual pet.

bear in mind a lot of this rewrite in common lisp is to make preparation to port to ulisp so i can actually physically realise the lil game.

so i want to be able to fit everything onto a 16x2 LCD character screen. i do not imagine this will be difficult as the pet itself is a one-line emoticon.
