The First Test Build Is Now Available
This public test build includes the first 7 levels of the challenges mode. The story mode is not available.
After years of redesigns and prototypes I didn't like, I'm finally happy with how this project is shaping up. This build is a huge milestone for me, I hope you enjoy it (just keep in mind this isn't a finished game and there may be bugs I haven't found or fixed yet, although I've tested that all the levels can be completed with a 100% score).
You can check the Current State, Roadmap and Known Bugs topic to know more about the current state of the game.
