Very unique concept! The first few rounds the game didn't stick with me very well, but after i discovered the different modes it became a bit more fun.
Around round 10 in my final plathrough the game became a bit too easy and I didn't really have any challenge anymore of trying to survive. Keep picking the more flies and spamming exploding froggies was the best strat here. Played until round 25 and died to a frog spawning on me -_-
I really liked the concept though! Would be cool to see more added to flesh things out and to keep the gameplay more fresh, with maybe even a cap to how many rounds you can play like Vampire Survivors. Definitely a strong base for a full game!
