Hi, thanks for playing!
That's some good amount of honest feedback. Did that enemy spawning happen in other than first 3 levels? In first levels we spawn a little guy to give some goal to the player. In later levels, the max distance could have been too low. We plan to tweak enemy spawning in the future, currently it's still too random.
As for variety for Zooids, we wanted to start with 4 balanced Zooids for each Breed and we might have some drop-only variations of less balanced ones. Thanks for suggestions
Rest of the points are valid as well. Looking forward to hearing comments from you on future updates.
