Hey,
yes, it also supports singleplayer. However, you need a stable connection and an account to start playing!
Hello there again,
as this was our first game and thus very non-optimized, expanding or releasing updates regurarely was almost impossible. That's why the game won't be supported anymore, but the servers (and we) are still running so no worries :)
Nevertheless, thank you for your feedback, we'll take that into account when there's something new to the game! If you need any help or have suggestions, feel free to ask.
Actually, if you played the game, did you manage to overcome level 3 - would be nice to know!
