G'day LG,
I'm awful at UI, but potentially I could contribute to some of the other programming tasks. I generally prefer working on game systems and logic. 10 hours every week might be a stretch for me, though I could definitely manage at least 5. If you have non-urgent tasks that I could chip away at, or just smaller discrete tasks, that could work. If you want to discuss, please contact me on Discord - my username is ryan89
