I only found the game called My friend's soul in the download section so I played the game. Very fun games, the friend mechanic and trap mechanic is awesome. It is challenging and quite fun. Keep up the awesome work!
Edit: I've played the PumpkinTD, I got to say it is very fun, to sacrifice yourself for tower defense. Very interesting concept. A monetary system would be nice since the amount of people to sacrifice are almost infinite! But very fun game nonetheless!
