Interesting concept! It's like an on rail shooter.
> The idea is interesting and gives a twist to the usual platformer.
> The art is also good, although maybe consider putting some animations if you continue to develop this game.
> I think one of the confusing aspects of the game is that it's not always so clear what you have to shoot and there's very little time to react. I think you can improve the idea by (1) rebalancing the speed of the game and (2) thinking of ways to better telegraph the objects that need to be shot to effectively communicate to the player what to do.
Overall good idea! Good job and thanks for the game man!
P.S. Please consider playing and giving feedback to our game as well! We are in need of more ratings. https://itch.io/jam/gmtk-2018/rate/300343
