I got to 2. Towards the end it's somewhat random. The issue of getting stuck with repeated is slightly annoying. Does the player need more control, to raise the skill cap? Losing my entire state when hitting R increases the randomness. If I had a true "next piece" display I feel like there could be a version where I plan out a long fun chain

I also got to 2, though the closest I actually ever came to winning was an eight made up of two tetrominoes, just not the ones I needed.
