Thank you. I was considering a different control mechanic, where you would press in the direction you want to up in, for example, pressing UP on keypad and you would rotate (via shortest path) to the top, but this one is the first one I got working, so it stuck :-)
Thank you very much for the feedback! I agree completely. The UI needs work, and I was planning on adding some more interesting enemies, movements and bosses, but didn't get the time to do it unfortunately. Maybe next time :-)
