The start felt too slow, but it makes you feel the exponential growth of the swarm, so I don't think you should change it. Dont really have any suggestions tho.
Ok thanks for clarifying!
There is a cheat to spawn more locusts (space) but I think it just crashes it on HTML5.
And ok no worries! Thanks for the feedback, it’s been very helpful! Would you be interested in testing future versions / projects?
