Nice work on every part of the game, congrats! I scored 13,736 points. I’m not sure if that’s good or not, but I had fun. Well done!
I have two suggestions and one question.
First, I couldn’t really understand the purpose of moving the screen left and right. If it’s meant to give the player more freedom, I personally didn’t feel the need to use it much, since the ducks already come toward the screen. I’m curious what your intention was with that mechanic.
For my first suggestion, I think not every duck gives the same amount of points, right? It could be nice to add a small score popup effect above the duck when it gets hit, like in many games. Seeing how many points each duck gives would feel satisfying and clearer.
My second suggestion is about reloading. I think being able to reload before the magazine is completely empty would give the player more flexibility. Having to wait until all bullets are gone can feel a little restrictive.
Good luck with the rest of development, my friend!
