🎮 In this puzzle, if you guess right; the hypotenuse rises and unlocks the path.
Guess wrong? It sinks into the floor. No pressure. 😅

Blueprint based sorting in #unrealengine for any type array is hard. However, in a lot of use cases, you can use bucket sort, which is what I did to sort the learning items in @cuprum2929.vaslabs.io
Each item has an order integer >= 0 which is used to index in a prefilled array

What is your strategy with #Steam Playtest? I've let around 120 people in, is it high is it low? @cuprum2929.vaslabs.io is not yet fully developed and we're planning to be at 80% of the EA version by the Steam Next Fest. I want to get some feedback as well...
