This is a really great start to the game, the Audio along with the visual style and graphics where really good, there could be some things to make the UI look a bit better, maybe some rounded edges or even a better color then the standard Unity button. Overall the game was pretty interesting to play, The END Tutorial button didn't work until the game over screen and it was pretty confusing on how you stopped the birds during the tutorial as it didn't explain it. When the game over screen came up I wasn't able to push Play again and had to close out of the game in order to restart it which isn't Ideal. Overall for a game that you made solo for the first time This is a REALLY good start.

a few things I would look at updating and or changing at the end of the jam is 
- Updates to the UI to allow the "End Tutorial Button" to work
- Add an option for windowed mode, as some elements when full screened where at the edge of the screen and i was unable to interact with them well (I.E The volume slider on the menu screen) 

- Updating the tutorial so that it explains how to stop the birds then just telling me i have to stop them. As well as making it so in the tutorial there is no fail state, just explain to the player that when birds finish attacking the crop that it results in game over so the player has a chance to learn the game.

You have an amazing start to the game, those few changes and I feel this could be a great add to your portfolio!
