Thank you so much for loving our game! We are currently working on the full version of the game, which will have more content to offer!
Regarding the bugs you mentioned. We have already addressed them in new versions. However, we have decided to keep the demo version on itch.io as it would require additional time and resources to switch it out.
As for the engine change, we have decided not to switch at the moment. We are already halfway through the development of the full version.
Once again, thank you for enjoying our game! Feel free to follow us on Twitter at https://twitter.com/Cato_TeamWoll for updates and news!
