Well it should soon be available (just waiting for approval from the admins). Version 0.14a fixes a few bugs, adds in floating point text for monster kills and soul heart pickup, some text to let you know the game is paused, and re-tunes levels 6 thru 10 to spawn 30 monsters each wave rather then the previous 40.
As always, your feedback is very much welcome. If you play test the game and find a bug, have a comment or suggestion, please don't hesitate to let us know either as a comment to this news post or on our IndieDB forums.
Thanks and have fun! :D
