Thanks for the nice feedback.
Yes the allies are limited to 2 and have a 1 round cooldown. The plan was to visualise the cooldown with a lock that appears over them and the limit of two allies was supossed to be implemented in the tutorial. But in the end I ran out of time and somehow the game just broke.
So I don't really think I will keep on developing but if I do I'll consider using your ideas (espasially the improving of the world).
