a few unnecessary things in the map like (1) mines around blocks - either way too much of it - or the way it was placed above the rocket launcher on the left (2) 6 shooters in the exit area were not effective - even 1 wouldn't have been effective (3) some gold placement was way too difficult to get - like that on the right of the thwump with the mines right by there.

the tileset looks nice though.

at the end, there's demo data. Delete it :p

Hate to be the bearer of bad news, but you NaN'd the exit switch, and the map seems unbeatable.
