I have finished Brackeys “How to make a video game”, what should i do next? A new tutorial or a project by myself entirely? I have thought about a western arena shooter, will that be too hard? Thanks in advance.
I suggest you to follow one more tutorial like tower defence just to consolidate your knowledge but if you feel brave you might try to start developing your arena shooter while learning useful techniques and discovering new tricks from your mistakes.
I wish you good luck, let us know how you will procede and show us you results!
