Hi,
thanks for feedback! The game was done for a school project and only some more minor things will be changed, before we stop developing it :( . Saving the game is in the works and hopefully will be ready soon. We know about the bugs, and will surely fix 1 and 2, but not sure about 3. If you want you can check the source code here: github.com/GytisDev/Game . Thanks for trying it out!
