It's pretty okay for a 72 hour jam, I got confused at the controls at first but got the hang of it later on. One nitpick I have for the game was the apples, I probably missed on what it was supposed to do but I think it was supposed to give back health? 

But anyways, as for the game mechanics, the scythe was a little slow to catch some zombies, and the game would've benefit from more faster gameplay. I guess some variety would also be needed because after 4 minutes into the game, it started to feel a little repetitive. 

But overall, still a job well done for doing all of the assets, and mechanics by yourself and this would be worth a learning experience. Keep jamming!

Nice

Some good potential here. I think it would make more sense if you could swing and hit the apple to regain health rather than clicking with the mouse. That part didn't feel intuitive. Nice job overall!

You should try to add some sound at least, with just little details you can improve your games much more.
