Nice one. I spent about 15 minutes playing, thank you.
I think I broke it a little, playing around with INT64_MAX - https://mathstick.github.io/play?q=hrojihaacciabcmtskiistbij...
Edit: mostly directed at OP, the puzzle maker claimed something like 12 identical solutions for the same puzzle
Would you be willing to add a manifest so this can be "installed" as an app on Android?
Nice! What did you build this with?
Also, submit it to https://hnarcade.com :)

Mathstick 2 is now ready!
Same as my first version, you can earn sticks to unlock the next level and the challenges get harder as you progress. With the newly added Puzzled Maker, you can now create your own matchstick puzzles and generate a shareable link to stump your friends :)
For example, check out this custom challenge I just created: https://mathstick.github.io/play?q=ktoylsjcnmylbetuinmylielj...
Feel free to share your puzzles below and feedback is welcome.
