Good game! A rails shooter is a fun thing to play, the music and the enviroment we flew through was very nice and it was fun overall but a few things could've been polished up.
We need a health bar to know how close we are to losing the game. Along with that we need some SFX or effects when we're taking damage, same for when throwing rocks and when enemies are destroyed. More Sound Effects and Visual Effects would have gone some way to making the actions more impactful and satisfying.
The enviroment could've also done with a few more splashes of colour too instead of it all being just grey. There's a point where the camera suddenly snaps to sideways view, I feel it could have been smoother and less jarring if it was a transition.
However, good job on the game! The rail journey was very nice and entertaining, music was good and flying thorugh the enviroment was very fun.
