I had a good laugh haha, just when I was thinking that the game had nothing about scale ! really cool  xD
Its a fun and enjoyable game, feels great to ram through the level when you are a giant frog , art style and musics all match the game style very well. its a solid game, congratz! :D

This was such a cute game.... There's not much to do if you're bad at it tho...Sometimes I got stuck cause I wasn't big and flies would either take too long to spawn or be too high... Went from 88 to 29.80 after a few tries xD That's not getting any lower I think lol

Haha, it was a nice fun game! Cute frog, sad flies xD
Loved the music for tiny frog (sweet & innocent) and large frog (boss mode xD) 
My time was 57.07seconds.
Currently I see the game as a speedrun high score obtaining game. You could also include flies eaten as a metric for score generation rather than just the time. Or the number of times the frog turned massive. 
For an additional challenge you could add some frog enemies like a snake slithering through the ground because currently there's no one to challenge the player - not the environment (hazards like fire/pits/wells/spikes can be included) nor the flies (they don't fly that high neither do they evade the frog's tongue which could be challenging).  It would be interesting to navigate the area when you're tiny avoiding snakes or other hazards adding a tactical platformer feel to the game. Of course, when you're a boss you could just squish the snake. Also a timer or indication for how long you will be in this form would also be interesting to see.

A really simple and fun game! I really like the hopping movement, and the frog is so cute! But after eating so many flies, things become SERIOUS and INTENSE. It's so funny LOL. Breaking through the blocks is also satisfying! My highest score was 16.32 seconds. I had so much fun playing! Great job!

A very nice little game! I quite enjoyed the contrast between being a little froggy duder, and a chunky rocking out beast of a boi. Very cute sound effects. 

The gameplay is somewhat simple, so if you were to scope this up, I would love to see you explore the design space of potentially having a few areas where being small is actually an advantage; thus creating a push and pull between being massive or being smol.
