Wow, very smart design iqncoorerpate the count down theme. This game gave me a lot of inspiration! Great Job.
The only thing (probably just to me personally) I would like to note is that using number keys for ability is pretty hard for me without a num pad. It would make the game much easier for me if there is a keybinding. (I know keybinding is really out of scope for jam games, so I won't really take out points for that)
Overall a great entry!
