Cell entities that differ based on position should not be cell entities

[city41]

createLevelData is greedy on cells in the x direction. Usually this is fine, but it can cause issues such as this level:

Ending up like this once played:

This is because createLevelData divided up the water into three rects trying to maximize x. If it had maximized y instead, the result would be what the user expected to see.

Allow entities to indicate they prefer greediness on a certain axis to fix this issue.

hmm, well allowing PoolOfWater to choose its greediness does help:

But doesn't solve the problem. The true fix might be to kill the notion of cell based entities altogether and instead a pool of water is created by using drag handles

The real solution is ChoppyWater, PoolOfWater, Waterfall and Lava should not be cell entities.

• turn them into standard entities with a xy drag handle
• write a level version migration to convert existing levels to the new format
