| My bad, I messed up with WebP images optimization, should be

| It's fixed now. Nice twist at the 4th level.

| Really fun game. I was happy when I thought I screwed up the
| final level only to realize my screwup was the solution.
| CodeCrusader wrote:
| Glad you enjoyed the mind-bend

| Fun, but only lasts about two minutes. Could be interesting in 2d
| or with some other gimmicks added.
| freehorse wrote:
| I think it lasting 2 minutes is actually an asset. Even though
| a 2d version etc would be quite interesting, it is great to try
| such little nice things and then move on to one's day, not
| everything in the internet has to take that long. And unless
| one wants to show ads or sth, there is no incentive to actually
| make it longer anyway.

| In 2D, it would become sokoban, wouldn't it?
| thaumasiotes wrote:
| No? Sokoban involves a single agent pushing blocks around a
| grid. No block can ever move without being pushed, and
| nothing can ever cross anything else.
|
| In this puzzle, the only way for anything to move is
| independently, and everything is free to cross anything else.

| If this was two dimensional, it would be the game Hi-Q, more or

| Solitaire removes the pegs that are jumped over. If this was

| jcjmcclean wrote:
| Really enjoyed that! I was surprised by how fun it was
| considering how simple it seems. Definitely would love it to last
| longer.
| CodeCrusader wrote:
| Thanks! Might play with more levels if people keep enjoying it.
| kazinator wrote:
| 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.
| Jtsummers wrote:
| How so? This is an old puzzle with lots of versions online, I'm
| surprised it'd be struggling with it (except for the twist that
| I'll leave out for one of the levels).
| parliament32 wrote:
| Why does it surprise you that a text generator isn't

| Jtsummers wrote:
| It depends on how it's explained. The puzzle, depending on
| phrasing, is not too dissimilar from other movement puzzles
| like river crossing puzzles. What I'm curious about is how
| it was explained to the LLM and how an answer was expected
| in response. You can probably even find text descriptions
| of solutions online so if you use the right keywords it
| would likely give a correct solution even if your puzzle
| description was wonky.

| Hah! Makes me feel better about struggling with level 3.
| H3X_K1TT3N wrote:
| I clicked the frogs, but nothing happened. Am I doing it wrong or
| is it broken?
| H3X_K1TT3N wrote:
| wait, I reopened the link in a new tab and it's suddenly
| working; not sure what's up with that.
| H3X_K1TT3N wrote:
| welp, that was short, but neat
| CodeCrusader wrote:
| Short and sweet was the goal. Cheers for giving it a go.

| 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):

| Glad you liked it! That last level twist was a fun addition --
| I wanted to keep things interesting. Your Python solver looks
| awesome, I'll definitely check it out. Always cool to see
| different approaches to the same puzzle!

| CodeCrusader wrote:
| Thanks! I'm not sure if there's an official name for it -- I
| originally saw the game a decade ago at my university and just
| recently decided to build my own take on it. It definitely has
| some Tower of Hanoi vibes. Let me know if you find an official
| name for it!

| As someone who is colorblind (Deuteranopia), the first level asks

| tell the difference between the two frogs.
| Jtsummers wrote:
| The frogs only move in the direction they face. Move them so
| that all the frogs facing right are on the right, and facing
| left are on the left.
| CodeCrusader wrote:
| Good call! The facing direction was meant to help, but I can
| see how the colors could still be tricky. I'll look into
| making it clearer -- appreciate the feedback!

| I am so pleased I stumbled on this little game by chance. Really
| lovely. Well done. Keep it up
| CodeCrusader wrote:
| Thanks! Really made my day to hear you found it by chance and
| enjoyed it.
| stanac wrote:
| Really fun. Third level was harder than fourth.
| CodeCrusader wrote:
| Ha, you're not the first to say that about level 3! I think I
| accidentally made the difficulty curve a bit wonky there. Glad
| you had fun with it!
| dgellow wrote:
| That was a very cute puzzle, well done
| CodeCrusader wrote:
| Glad you found it cute. Was aiming for that mix of simple looks

| Hey everyone, I'm the author--really appreciate all the feedback

| Quite cute diversion.

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