I‘m glad you enjoy it! sorry for confuse you about lack of ending indicate. The game has no clear end is really my design fault. The game was designed for a 5-10 min experience , and I tunned up the starting difficulty to letting players experience everything as quick as possible. I will polish it follow up.
I reload a Linux distribution on github https://github.com/tiomke/bubbleout/releases/tag/v1.0.0 , please tell me if still not work.
