wtf is rythm-game?

Rythmus Jumper is a small rhythm and platformer game written in Java. This repository is the public open beta build, which includes account login, cloud saved progress, online leaderboards, and replay recording, though the admin panel used to manage the game is kept out of this public version. To play it, you download a zip file, extract it, and run a batch file that starts the game on Windows. It needs Java 8 or newer installed, and an internet connection is required for logging in, checking leaderboards, syncing progress to the cloud, and uploading replays. The game starts in English by default, and every play session saves a replay file locally in a replays folder. If a player is logged in, those replays and their progress also sync to a backend service called Firebase. Because this is an open beta, the README says bugs are expected, and it asks players who find one to report their account name, the level number, roughly when it happened, what went wrong, and the replay file if they can find it, so the developer has enough detail to reproduce the issue. For anyone who wants to build the project from source rather than run the downloaded zip, the README gives the exact Java compiler commands used to produce the release jar file, including compiling every source file with debug symbols stripped and packaging it with a specified main class. The README also includes a short security note explaining that this public build has had its debug symbols removed and avoids storing obvious plaintext strings that would be easy to find by inspecting the compiled class files, but it is upfront that any game running on a player's own computer can still be reverse engineered given enough effort, and that the real protection against cheating lives in the rules enforced by the backend server rather than in the client itself.
