Alright. Was talking to Holmgang. He is totally fine with me joining your team as an artist for the upcoming HAGJ Jam.
Have some other artists applied meanwhile? If so, I have no problem with stepping back - I am pretty late with my answer.
If I can make all the game assets in time really depends on the amount and type of art you expect. At the end of my creators page I listed lot of different art styles I admire, would like to try out and feel capable to provide. Some are more time-intensive, some are less. Find any style there you would like me to contribute to your game?
