Currently there isn’t an ending beyond trying to get the highest score. We’re planning on adding a proper ending and a story including different types of puzzles and some objectives. Right now we’re just seeing how the core mechanics and basic elements of the game function and how well they’re received. We do have plans to add more though.
Also, awesome score! I think that’s the highest anyone’s reached by quite a wide margin, excepting one of the dev team. It’s great to hear you enjoyed the game and that you found the settings useful. Hopefully when we add more levels and some new powerups you’ll enjoy it even more!
Thanks for playing! :)
