it's really nice ! the controls feel good and the visuals are relly well done. you really have the impression of going fast. both clouds and background move a different relatives speeds on multiple levels so the impression is even better. The player controls are simple and really responsive. The game is fun with multiple waves and phases of enemies with a boss that has multiple paterns. The music it's catchy and fits the gameplay well and the 2D models are clean and colurfull. Maybe put a visual queue for when you take a hit and lose a live like making the player blink or changing oppacity. Otherwise pretty well done and really fun !
