THIS is the perfect example of a good game jam game! It takes a concept and applies it well, it's nice and short but has a good reason to replay to win, and feels pretty polished. I didn't want to stop until I beat the boss.
The only thing that had me unsure was the randomness of spawns. I had a map where stone didn't spawn for several rounds and I butchered one of two, so I had over a handful of enemies shooting at me until I could get the bow once. However, I also gathered a ton of berries, so I had a lot of health and time, so I ended up winning on that one. So maybe it's more balanced than I figured.
Art is adorable, it feels like the right kind of stress to beat the timer and good to succeed. Well done!
