Thanks! I have had quite a bit of practise over the last 6 or 7 months but i never actually finished a project. As for time management I basically just came up with an idea while in the shower after the limitation was released, and just went with even if it wasn't fully thought out yet, to give me as much time as i could to actually make the thing :D
Yours is impressive too for a first game jam, one thing i noticed in yours was the bat's animations, they looked really fluid and impressive
