This is the very first version of Bug Jump. We finished the game long time ago, however, I had trouble creating an executable JAR for it. So, it was never released to the public. Finally, after hours of debugging and researching how to create a proper executable JAR, I was able to make one that works.
This version could possibly have bugs as it is the very first playable JAR. If you encounter any bugs, please submit a issue thread. Thanks! :)
