So glad you figured it out. 100% my bad for not forcing my army of frog programmers to build the tutorial. It's a bit hard to type with flippers (imagine the PRs). So cool you stuck around to round 25 though! shame about the toad (ew toads) spawning on you, I did add some code to ensure that enemies don't spawn within the viewport's vision, so for that reason you 100% died to a bug and therefore, not your fault (it's the frogs).
Maybe I will come back and polish the game up. It seems yourself and a few others are interested ^^ Regardless thanks so much for playing <3
