Really creative way to handle the theme, sadly not really fun in gameplay.
The main issue for me was necessary to run from exchanging to the exchanger by foot, and our hero is not really agile. Yes, you can throw your figures, but most of the time they are actively blocking the path to it, so throw is no longer an option, maybe different routes for bosses to stand and shoot may fix it?
But besides the actual gameplay, the bosses are cool looking and music is awesome!
