I liked the retro styled art and sounds in this one. I found the game to be quite challenging given the time limit and the limited spawn rate of the air bubbles, which is a good thing. I also made the mistake of trying to catch the air bubbles with the frog’s tongue, lol.
If you decide to update this, I do wish the frog moved a bit faster, or perhaps more smoothly without the stop-and-go style movement. However, I also realize that might be more of a me thing and it would mean you’d have to re-balance the difficulty around that kind of change.
Overall, a simple, cute game. I liked it!
