Thank you a lot for this complete review and playing Neverest ^^
I'm so glad you enjoyed our game :3 To be honest, the cannons shooting outside the screen is a bug that we could not fix on time (Silly developpers :P) and I agree in the fact that it might feel frustrating. The pause between movement is here because we wanted to add a rythm bar inspired on Cript Of The Necordancer, but it was removed and the movement was kept anyways because it felt good. ^^'
By the way, I think your score is the best I have seen so far, congrats! We should have added a leaderboard, we'll try to do it the next time. ;)
