Really great game overall! First I would like to say it's very polished for a game jam and hits all the marks. The tutorial and UI is really well done and quite intuitive, something you don't see much of in gamejams, and it was really nice for it to be implemented in the game. Secondly the game is really fun. I had to strategies on the intensity to use the bow when the border got smaller, as well as think of ways to avoid enemies.
However even though it is really polished, there are a few things you could have done to go the extra mile. First off, though this is quite minor, more arrows would have been nice cause I felt the game was really difficult with just 2. Always remember if the game is easy for the developer, it's hard for the player XD. My second issues is user feedback. I found it hard to keep track of when I hit an enemy, and when I lost health. A few things you could have added were; sound fx for when you were damaged, screen flashes red when you get hurt, particle explosions when enemies died...ect... Anything to give the user more feedback.
The user feedback issue is only a minor inconvenience to a very polished game.
Good job!
Here is my stamp of approval✅
