Fantastically done! Love the story and Portal-like Cave Johnson voiceovers, as well as the BB8-like main character. The carboard feel was nicely present throughout with good warm colors. Really solid (more than cardboard!) 3D entry. I also appreciate exposing all of the filter options to disable to get it running smooth as we need/prefer. I was able to get to the end and unlock one of the secret areas.
So, basically the game is great, consider the below just the fine tune polish commentary, but not such that they really detract from my experience at all!
I feel like the ball should have a little more inertia, rolls to a stop so quickly which is super helpful and makes the game easier, but seems like judging a little bit more of a stopping speed could be fair too. Also checkpoints I feel like they should just be auto triggered instead of having to press e, but personal opinion perhaps.
Most difficult part was the floating blue portals/fans, feels like there should be some additional force helping you keep a little centered in them (though I realize that’s part of the challenge).
Minor UI bug: pressing esc to escape the Map would be nice, and also if you press esc on the map (bring up options) and press esc again, you end up still in the map but your mouse is controlling the view, so you can’t move your mouse over to click the x (if you remember to press m though, you’re good).
Final verry nitty nit pick: under UI settings, you have one slider for mouse smoothness. You have nice popups and text explaining how a lower number is higher smoothness… I’d just invert the logic, do a (1-value) or something, saves the text and makes it more intuitive.
