yep! Twitch Defense has an upgrade button at last 🙂
currently you can access the upgrade system after you’ve played through the game (aka died… as there is currently no win criteria.. but i am considering making it so that you can select between Infinite Mode and 60 Second mode. But ill see about that 🙂
remember, its still an early work in progress, but im working on it on a daily basis… when rl doesnt butt in 😛
to those curious, it was made with StencylWorks, a pretty easy to use, yet advanced flash game creation program 🙂
please post comments and let me know what you think about Twitch Defense in its current form… and also, I am very much interested in hearing what ideas on game design you might have 🙂
