The implementation wasn't too hard as I used the framework of many games I have done in the past for the basic stuff and intertwined, added variation on it. Most of the time went in the map making and in the art as I'm very slow with that. I had planned to spend a good chunk of time on it but then at some point the whole picture of the game clicked and I wasn't even noticing the hours passing by.
Thank you for playing! :)
