    Really fun game. I was happy when I thought I screwed up the final level only to realize my screwup was the solution.

    Fun, but only lasts about two minutes. Could be interesting in 2d or with some other gimmicks added.

    Really enjoyed that! I was surprised by how fun it was considering how simple it seems. Definitely would love it to last longer.

    Not being able to repeat a successfully solved level sucks.

    It would benefit from that model that is popular nowadays whereby higher levels are unlocked by solving lower levels, and you can choose to play any unlocked level whatsoever.

    Claude Sonnet 3.7 has a hell of a time with this.

    I clicked the frogs, but nothing happened. Am I doing it wrong or is it broken?

    Very cool implementation of a classic puzzle (with a surprise on the last level that I haven't seen before.)

    Years ago I wrote some example Python to solve the same puzzle in another game (with spoilers for level 3):

    Nice implementation. I've seen this puzzle before, does anyone know if it actually has an official name? Kind of reminds me of a variation on the tower of Hanoi.

    As someone who is colorblind (Deuteranopia), the first level asks to swap the green and brown frog. With the hues used, I can’t tell the difference between the two frogs.

    Really fun. Third level was harder than fourth.

    In some UK schools, this was the basis for a mathematics investigation for 11 year olds. Do the task for various numbers of frogs, records the results, and try to find a rule – then make a prediction for a certain number, and test it!

    A great introduction to the Scientific Method, and a fun activity too.

    Here's an example: https://spiremaths.co.uk/wp-content/uploads/Frogs.pdf
