One problem is when the ship enters a planet, the enemies can still attack you.
Other than that, both the audio and the graphics are pretty nice, the Oasis theme is well respected and original since it doesn't take place in the desert. The name goes well with the gameplay, so to me, it was pretty well executed! :)
If I remember correctly you are using godot. So in Godot, you would have to setup a collision layer for the player and another one for the enemies. If the player is an area2D, set monitoring AND monitorable properties to false for you area2D and disable the collision shape (the child of your area2D or KinematicBody2D). So On area enter, you disable all of that and maybe physics_process and process would have to be set to false. Hopefully it could help you! :)
