This is good
The first thing you'll notice about this game is its visuals. They are stunning. The colour palette is vibrant, cohesive and brilliant. The pixel art visuals are exquisite and the animation is great. This, however, is not an easy game. You'll die many times on bosses and some regular encounters. The exploration is also tough, and sometimes finding the boss is hard. There is some unrealistic pink blood that appears when the Drifter dies, or when he's on low health. The enemies also get beheaded if using a charge attack, but it's all very cartoony and realistic- there is no violence against humans here, just aliens of various shades of green or red. If your child is a capable gamer who is fairly mature, regardless of age, let them play this. However, I'm saying 12+ as a recommended age for the most immature children, but I'm sure most 11-year-olds can handle it.
