ABC 2025 patch 2

Added 2 new levels: 11 and 12 to the DLC, and converted level 6 as a new level to the free version.

Tweaked also the other levels more as this was a major patch. This included adding new shapes and replacing poorer shape ideas that didn't work that well. In general I didn't want the game to be as much a reaction game, so I took away a shape that was flying at too fast speed. In general the levels now have more shapes that move at different velocities, as it generates more interesting levels.

Pacing change: It felt like there's not much going on in the game if the music level was low, so I added the spawning of shapes and the levels are now more intense. The level difficulty was affected and the later levels are now more difficult in general. Tried to counter the difficulty curve bump by making sure that on most levels the shapes can't spawn quite as tightly as previously.
