So I saw your comment on not having enough time, but you managed to submit a game and the core mechanic is there - protect the tower before the goblins destroy it. Cool! I don't know if you have already got the Gamedev.TV Unity 2D RPG course but if using these kinds of assets and making this kind of game interest you then thats probably a good course to get. Depending on your level/comfort with building games in Unity is could be considered 'intermediate' and its a bit more advanced than the 2D course, just FYI if you are interested. Its a great course. Good job on getting your entry in and I'll look forward to what you submit next time! :)
