Thanks a lot for the detailed explanations!
As for increasing spawn rate, we do have this, depending on how many time elapsed, the spawner does it a little bit quicker, but it's not easy to notice it as the game is very frenetic hahah
Yes, the sacarabs spawning some times is frustrating I agree with you, I'm thinking of making them always coming from some spots on the scenario, such as from the mouth of a snake statue and such
Again, thanks for the feedback and I'm glad you had fun with it!!
