The Steam page has a demo available for play with the first 10 of the 35 levels. It’s somewhat outdated in its UI and how certain features work and the cutscene assets have seen significant changes but the levels and features are accurate to what the final game contains. I’ll replace it with a more up to date build when I have the time.
The full game is releasing for £3.99/$4.99 this December.
