Phoenix Vision – a comprehensive modification of the game’s visual aspects.

I think it's a very good decision to make upgrades more than just different color variations! :smile54:

Well, it's also an option for variety, although there are already enough differences between upgrades ;)

If there was some kind of pattern for creatures of "non-standard" size, it wouldn't raise questions, but as it is, it's unclear what principle the developers used to make them shorter or taller than the others.
