Really fun and charming game! I really liked the charming aesthetic and I think the silly music really fit the game.
If I could add one thing is that I wish that the shooter games kept shooting if left click is held down, and that the third game had a way to be beaten faster since you have a timer, and having to wait around with a timer ticking down doesn't feel great.
Those are small details though and don't detract much from the experience, overall you did great, especially for your first game, good job!
