Nice! You should have unchecked the "export with debug" checkbox before exporting.

I liked that the title bar said "Spider King (DEBUG)" - I don't know if it was intentional, but I thought debug was a funny pun for the game. It was quite repetitive and once I died to the spider king I didn't really feel like killing all of the spiders a second time.
The graphics were nice

Wow, that was a lot of spiders, and the Spider King is really huge! A nice game, I would just like to see a little more variety and maybe some power ups, for example to refill your hearts.
