DEVELOPER NOTE:
There is a known bug that only happens with the browser/web version. At the end of the game (wave 5/5, 10 minutes after the game starts) the browser version of the game crashes. It is supposed to be the ending of the game that should show an animation and return to the main menu, but in the browser/web version it crashes. This doesn't happen on the downloadable export or in the game engine itself, just the browser export, so I must assume it is a game engine bug.
There are a few other minor browser-only bugs, so if you want the full experience I would recommend downloading my game. Thanks for checking out my game!
