I played your game, here's a video of it.
Hey onefourtysevenam - thanks for trying out our game. But this is a very old beta and I think we might've missed updating here on itch. Apologies!
Since then we've released a full version of the game in May 2018 on Steam - which is a lot more improved that this extremely patchy beta.
