Looks like I wasn't able to finish Tetrarune before the end of 2025. I really underestimated the amount of work needed. Luckily, most of the hard parts (game engine, block patterns and other backend stuff) are already done. This is a quick demo made with the parts I've completed so far. Expect many bugs/issues.
