I had a good time! Wave 20 was quite a sudden jump in difficulty hehe. Thematically I feel like it didn't incorporate the cookie thing so much, but as a week long project TD game? Fun!
Thanks for trying out! The theme "Risk it for the biscuit" actually means you need to risk accepting an offer in order to get a reward / benefit so it doesn't really need to be related with biscuit. Having the idea of cookie as your currency and HP is just an extra thing tho!
