Very interesting and fun game so far, besidee all the glitches and bugs, but thats what a beta version is for, developping. So here's a few things that came up to me:
I think it would be a good idea to make the annoncement window smaller and also placing it at bottom of the screen, I find the screen view jam packed. All those icons should be smaller and/or come with an hide button. Another nice add would be an escape button in the arena battles replays screen.
