I have no idea what this has to do with 2020 but it was pretty funny! Clearly you had a lot of fun making this, and I had fun playing it - although I'm not entirely sure if I finished it. I ended up doing some exploring though and found some funny things like the bloody axe behind the building, the UFO, the herd of cows, and the elephant and catapult near the nuclear towers. Were they there for a reason like you had plans for them but didn't have time to add them? Or something else? Either way, funny game!
Some minor critiques: When shooting leaves it seems to shoot off-center, I found myself having to constantly aim a bit to the right of what I was trying to hit. Also, the text above peoples heads can be difficult to read and it doesn't always seem to be where it should be. There's a bit of a clash of visual style going on, for example the tree creature at the beginning and the ruins area are all a very different style than the rest of the environment.
