It was quite fun actually. I like the idea you get to pick up other ducks to shoot with you. Perhaps after the jam, you can replace tomato to something relatable to ducks.. perhaps reverse the usual nature pray... like duck's revenge. So instead of tomato, perhaps change to something like alligators or eagles flying across the screen. And the arrow is a bit thick, i think instead of that since this is a mouse game, put something where the pointer is can hint where the bullets (or shoot out duck spits?) and try to drawn the eagle or disgust the alligators to sink LOL. Not sure, but you do have the fun element and the control is smooth so the game is kinda fun to play.
If you get time, please try out my game and give me some suggestions too! I can see that you do have good ideas so perhaps you can help me with some to help me improve my craft. This is the first time I make a game and join a game jam so took me awhile to figure out what to do (or just have ideas what to do). But I love playing others game too as I feel i have so much to do still.
