An interesting first game. The voice acting in the starting cutscene was very well done and the pixel art for each scene looked nice.

Tips for other players because I didn't see instructions written beyond the main menu instructions and it is somewhat unclear what the choices are due to them being obscured by the unresizable window.

You have to be both in range of zombies and click on their sprite in order to damage them. The zombies appear to have farther range than you do.

You must kill all the zombies in each scene to progress.

Space bar reveals some story and choices for each scene after the first. The choices reduce your party members by sending them elsewhere which affects the ending?

The percentage on the left appears to be affected by the use of your time ability which rewinds your and zombies  movement within the scene. Perhaps there is some tech with this that makes fighting the hordes of zombies safer?
