Hi, thank you for playing and most for the feedback, based on which I included a TL;DR version of how to play the game above the long one. I'm also pasting it here:
TL;DR
- [SPACE] - Switch between dimensions
- [LMB click on ground] - Move to position
- [LMB click on a cube/small button] - Move to pick a cube/push a button
- [RMB click on a cube] - Teleport a cube to another dimension
- [RMB click elsewhere (when holding a cube)] - Gently release a cube
- [MMB click (when holding a cube)] - Throw a cube
- [Scrolls Wheel Up/Down (when holding a cube)] - Adjust position of a grip
- [TAB] - Open in-game menu
