Hi I generally do agree with most of stuff and its a fair feedback overall.
UI and audio and even idle animation were in scope of the jam but life stood in a way this year to work on games : D. As for mouse/keyboard stuff I generally find it is very preferences based but I do agree for more laid back mouse would maybe be better(although tbh it's not like you have 2 hands on a keyboard right now to play this). Truth be told keyboard controls translate better to gamepad 1:1 and that was the main decision factor. I don't mind giving the options to choose.
If you're interested - I am planning to go towards steam release with this and there will be at least few demo versions to give feedback too. In general thank you for taking time to give me feedback :). Much apprecaite
