Finally!!! I beat the easiest level!!! LOL
So, my biggest complaint is the steep difficulty when trying to learn the control. It's quite difficult to aim for the farmer. It took me about 5 restarts or so to be able to hit the farmer somewhat consistently (read: skill issue). I think lowering the difficulty can help smoothen the gameplay experience. There are a lot of ways to do this, one that comes to mind is to make the farmer not shoot the geese until the player hit the first farmer. It's because, at some point, there are lots of farmers in the game that it's almost impossible to target them with all of the bullets on the screen.... which in turn, makes it harder for me to learn the aim.
Once the geese become larger, it becomes easier to target the farmer and at that point, I've become comfortable with my poop aim (I can't believe you made me said this lol). When the RPG farmer comes, it doesn't seem too challenging.
Now onto the good part! As others have mentioned, I think the art, the music, and the SFX are great! It mixes together nicely with the gameplay. Good job on that part!
Also, for some reason, I have this strange feeling of satisfaction once I defeat the easiest level. It has the feel of a souls-like game to me just because of the poop-aim mechanic. I think you can somehow take advantage of this (maybe with another type of bird with a different mechanic or harder types of enemies).
Overall, great job!
