Since it appears geometrically impossible to go beyond BH + Sun, and BH + Sun is already very hard to get, I think 1 BH should combine with 1 Sun to do something, even if it's just clearing the screen and scoring lots of points. Currently, there is no reason ever to leave BH in play! This is undesirable for gameplay because BH is the coolest merge.

Also, it would be nice to let us save > 5 bullets.

Also also, game totally crashes Steam Deck if you exit using the game's exit menu as opposed to telling Deck to force quit the game.
