Well here is your chance! I've finished work on The Clockwork Engine B4, and i'm looking for testers! I'm about to write a readme for it, which will explain everything that i can think of about it and how to create your own levels. NOTE: I will be distributing the betas WITHOUT any levels to encourage you to make your own. This helps me judge several things, including ho easy it is to use, as well as having lots of diverse environments that will be tested.
If you want to test, post here or send me a PM
