Solid concept of defending the moon from alien invasions, however, the loading time is quite long and could benefit from some optimization. The sound design could also be improved, specifically in regards to the mixing of the shooting sound and the background music. The difficulty level of the aliens does not seem to adjust according to the player's progress, making the gameplay a bit repetitive. The graphics and theme of the game are visually pleasing and the music is engaging. Overall, the game has potential but could use some adjustments in terms of loading time, sound design, and difficulty level.👍
