We have just submitted the build for Steam Approval!
We're hoping it will be approved, and we'll be keeping an eye out and adjust for any feedback we get.
Right now we have entered a mostly polish stage, making sure the game is fun, clearly understandable (for instance, as above, these tutorial panels) and looks good! Lots of internal testing too.
To be fair there are a few things that still need to get done - Sound Effects (like button clicks, menus, or environmental noises) is looking like it's next up, but there should not be any blockers or delays at this stage.
We will keep you posted!
