Hello! Welcome to Feedback Quest 6! My name's Hythrain, and I'm one of the hosts and streamers for this event! This feedback is being written live on my stream.
So since my old save data was working, I started off with what I had and went into the next level I could. However, upon completing it I... couldn't get out. XD
The only real thing I can comment on are the blocks you have to hit to disable. These don't work with your regular shot and there are times where you simply can't jump through them without getting hit. This is about the only thing I can say is not in good design: if an obstacle is unavoidable, it makes the player feel like they're being unfairly treated.
