The art style is quite distinctive, and all goes together very well considering the amount of different pieces you have. Placement is a wee bit clunky, but that's easy to fix, and it was fun making a little bullet hell for the bugs!
Sure! It seems like the areas for placement don't exactly match up with the lilypad graphics, so sometimes I'd find I was unable to place frogs where it looked like I should be able, especially once you get a large number in the same area. Hope that helps!
