I've just updated my game. The main changes are below.
1. Multiplayer has been added: now game is playable over the Internet. To use this feature, press Alt+C after launching the game. The idea is quite simple: host player generates session ID, client player enters this ID; so host player should provide the ID to client player. It uses HTTP-bridge for data exchange; if anybody is interested in the bridge, I can provide you it's PHP source code.
2. Reorganized resources: now images and music are outside the executable.
3. Some bugs have been fixed, but I don't remember which ones (: Probably I also have added few new ones :D
Let me know if there are any issues.
Enjoy! (:
