It's great to see a fresh take on using death in order to progress.

Certainly an interesting idea, and with the limited number of lives you could create some very thought provoking levels using what you have here.

As for the levels (level?) of the game as it is now, I think I encountered a problem when I tried to leave the level. I thought of getting the sparkling item before leaving the area, but I couldn't manage to collect it and leave too... maybe I suck or maybe something went wrong, maybe you can tell me. :P

As a game, it requires a lot of memorizing which is fine for a short game like this.
If you are planning to continue developing this, add an enemy respawning feature to eliminate the possibility of dead ends. Also, there's no way to restart game other than refreshing the page(?)

The use of theme was there and I liked the jingle that played when you got turned into a ghost.
It's a pretty good start for a (possible) bigger game too!

Really great idea, one of the most inovative that I've seen this jam. The game is kind of buggy and not really polished, but I guess that's understandable for a jam.

Can you add info about which keys to use?
