Penguin is a 2d esolang.

Commands

Command	Name	Description
P	Penguin	Moves left to right by default
/ \	Slopes	Redirect penguin up or down
|	Wall	Redirects penguin back (left to right —> right to left and vice versa)
c '	Carry	Gives penguin symbol between c and ' on its move direction. Any symbol between c and ' does not count as a command.
i	Input	Asks for user input (1 symbol only) and gives it to penguin
e	Execute	Executes current symbol penguin holds as a command
#	Halt	Stops penguin (and so the program itself)
s	Say	Penguin outputs the symbol it holds (and the symbol disappears)
_	Ice	Moves penguin to the next cell in its moving direction

All commands are executed only when penguin touches them (it must touch the beginning of the command, e.g. c in cA').
