Partially agree with previous but partially it's my own fault - I definitely also tried to jump as a tadpole...oops...but overall it was cute, frogs were definitely a favorite trend across designers with this theme, and you had a good interpretation of it too. Making it so you only evolve when you get X amount of collectibles is a good way to progress by making the player explore all possible areas with their current evolution first (I didn't even consider walking left at first, until I realized I had no more bugs to eat), adding challenge and ensuring they aren't progressing in the wrong order, and it also makes sense thematically. Congrats on finishing your first game jam! Hope you will participate in many more to follow, if you liked the experience!
