You can scroll to look up and down.
I didn't want to make the skill descriptions appear every time you hover over them because they got distracting while I tried that out, so I made it appear on right click (cursor changes to a mouse showing right click as well). Most people learn what the skill does quickly anyway, so showing it constantly wouldn't make sense.
I'm planning on releasing this on steam this year. The jam version will get some improvements and bugfixes but that's all. If you want to get notified if stuff happens, then I have a discord invite link to a server on the game page.
Thanks for playing!
