That's a great catch! Looks like we forgot to ignore letter case on some of the parser inputs. Thanks for pointing it out - we'll try to get that fixed soon.
We've gotten the game updated to version 2.5.1, which fixes the issue you found along with quite a few others we spotted while doing some troubleshooting. Give it a shot and let us know if you spot any other problems! Thanks again.
Unfortunately, we have no plans for a non-browser version at the moment. We actually built the game for browsers specifically since we hoped that would make the project more accessible for everyone.
