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.
