Glad that you liked the sounds! have debated whether to add an Arcady music, but happy to know that the ambient forest noises was a good choice.
Funny you should say that, I only also noticed that strategy on the last 10 hours before deadline (almost did not notice it due to my sleep deprived brain). That's why I added the attack cooldown and the faster red frogs. It did helped a bit, but did not solved the issue entirely.
Nice idea with the non-alien frog, thank you for playing!
