play nicely with the repl

this issue is bigger in clj, remember in cljs the game runs in the browser so the terminal taken problem does not exist.

Still targeting both, if we fix this the clj version may make more sense for development.

• [ ] look into proper fighweel workflow. try to preserve game state instead of restarting when code updates
• [ ] run game or parts of it from REPL (exit dont kill process)
• [ ] add debugging capabilities to a running game, for example print game map (all or specific parts) at any moment
• [ ] develop/test from the repl

this may be less relevant considering #50 although the figwheel part still applies
