You won't know what you are making until GDKO starts so as long as you start and submit during the window you'll be ok.
thank you, also I forgot to mention that, I will start late and end early for sure (base on construct 2025 jam schedule). I already reached out on other jams, just waiting for the responds. also I'm not trying to win it all, just want to make something good and small polished experience. thanks for the approval :) Happy Holidays to you!
