@scornz, @florian-van-strien, and @svarttand. Thank you very much for your feedback!
About having screenshots on the page, unfortunately I haven't been able to upload images, as the "upload" button doesn't work. I think maybe it's the browser, so later on today I'll try to install a more mainstream one just for that (I use Palemoon).
Also, there aren't health bars for the defenders because I didn't managed to do with the positioning, as they come back and forth (the enemy's health bars are anchored on a general "Rift Canvas" and only get visibility on/off when there are or aren't enemies on the rifts). But I guess I just figured out how to do it. Yes, this is the second jam game I program all by myself on my life, and the first one I got something near playability, as I'm not a full programmer, just a Game Designer who like to try to code. :)
I'll improve the rest of the UI on an "off-jam update" and leave it for the ones who want to try it. Expect something tonight (Brazilian time...).
I'll also try, on that update, to make some form of ingame tutorial to ease the start of first-timers. :D
EDIT: The researcher being able to cure and research at the same time is a bug. Nobody is supposed to multitask here. I'll adress that, also.
