Played the Windows version as I saw the comments about issues with the web build and happy to report it ran glassy smooth and bug free for me :)
Really fun puzzler, which turned out to be a lot more difficult than I expected! Stages feel well put together and do a great job making the player explore different ways of configuring boxes.
Particular praise here to how polished and juicy this all feels, from details like lighting or movement particles, the feel of breaking the boxes and even just the attention to detail with different sfx for different UI interactions. It all comes together to make this a pleasure to play.
