Metroidvania in Lisp

This was originaly made for "9 day Metroidvania Jam", but I was 2 weeks late :P How to play Left and Right arrow keys to move.Up arrow for jumping.Z - attack with sword (if you have it)X - Defend using shield (if you have it) If you loose all hearts you will have to reload page to try again (It's rough I know).And there is no victory screen, if you get to the room with "GZ!" written in blocks it's the end and you won :) Techincal Side Game is written in Wisp (lisp-like languadge interpreted in js or compiled to js). And no engine was used, canvas and code only.
