A fellow frog game! This game looks fantastic—the different types of frogs are very well done and are distinguishable at a glance, and of course the arcade-style callouts are delightful. "Spicy frog" never fails to make me grin. Tower defense balancing is always difficult but you've done a good job of it here.
I think my one quibble with the stages is that for Stage 2 in particular, there's nothing indicating that the bugs will make a loop around the track! I'd assumed that they'd split at the fork and rejoin at the other side. Not a huge deal, you figure it out after the first play, but something I thought I'd mention.
I look forward to revisiting this post-jam when the known issues are cleared up!
