Open Source Java Real Time Tactical Games for Mac

The mech platform floats through levels and progresses over time. It differs significantly from traditional Tower Defense or Survival games. One of the game's key features is the fine-tuned balance of hundreds of gameplay parameters, based on player-collected statistics. However, this feature is not yet fully implemented — it requires a server machine, which I currently don’t have due to personal circumstances. If anyone can provide a server machine or a service like Google Virtual Machine, it would be highly useful and greatly appreciated. The game is written in pure Java using a custom engine. A Java developer or designer is welcome to collaborate on the development. As the title suggests, the game is not yet finished, but it is playable. Developed solo over half a year, with 500 KB of source code and AI-generated graphics. As you can see from the screenshots, the game is designed in a pixel art style. One of the planned features is multiplayer. Your feedback is welcomed.
