I liked the game a lot once I understood what was going on, which took me one or 2 playthroughs.
The menu UI was good, and I liked the style, but maybe a little bit of padding on the main menu buttons so they aren't right up against the edge of the screen, as well as an offset to the curser image, i found myself not knowing where I am clicking exactly in the menus, and then hide the curser image in game so I can see more clearly where I am going to be placing things
Guiding the chickens was a blast! I enjoyed getting them into the ship, it was very satisfying. Maybe having a count down for how many chickens left before the ship takes off would be nice, as well as a better way to track the chickens? Chickens kept dying off screen and there wasn't much i could do about it cause I couldn't keep track of them all. Maybe a radar or a zoom in/out feature
Leaderboard looked nice AND clean. I loved the art style of the game. everything looked like it was the same style. Overall, nice job for only having 3 days! cant wait to see what you make next!
