4D Intuition

I really enjoyed the game. It is truly 4D and, most importantly, perfectly illustrates the 4D concept, allowing you to compare 4D mechanics with their 3D counterparts. For me, the difficulty spiked exponentially when I had to start [spoiler]taking photos of a 4D die from different angles[/spoiler]. The game pretty much stops giving you explanations at this point, forcing you to really rack your brain. It heavily reminds me of the "how to draw an owl" meme, where you get the bare basics and are suddenly expected to draw a highly detailed, realistic owl. I would absolutely love to see this game in VR. I believe that being able to perceive depth—at least for the 3D objects—would make solving these puzzles both easier and way more engaging.

Absolutely genius UI system, this is easily the best game that I've played at giving you a real "spacial" understanding of 4D. It isn't as pretty as other 4D games, like 4D golf, but I feel like I can grasp complex level design much easier in this game than any other. Only thing that I wish the game had was better keybindings. It's clearly meant to be played primarily with a mouse, which is fine, and it's definitely still playable on a controller. But it would be much easier to play on controller if I could set keybindings so moving the screen and turning the camera used different buttons, instead of just toggling between them. Buttons that move you in screen space would be nice as well (like a button that always moves you in the red/fire direction, no matter what side of the 2D screen the red/fire direction is). Oh, and there should probably be a better way to "rotate" in the "hyperplane illusion" view, it's very easy end up rotating off axis, and not be sure how to realign your view with the grid. I didn't have a hard time with that, but I could see it being very confusing if it was someone's first 4d experience. Still, great job on this, it's very well done
