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.
For a game made in 3 days that is randomly generated, it works well enough. However, as a game in general it leaves a lot to be desired. For starters, its difficulty is through the roof. I found very easy stages to be annoying and anything above medium downright impossible just due to how much stuff is going on. It throws a LOT of things you need to keep track of at you very quickly. Adding in the fact that the player avatar doesn't even keep pace with your mouse and it can become WAY harder to dodge things.
If there's any intent to do more with the concept, then there needs to be a better control as well as better balance for difficulty. Of course, I say this as someone who isn't a fan of bullet hell games.
There's sadly little I can offer for feedback on everything else. However, the music is VERY loud and peaks too hard, which forced me to keep it muted. You may want to change settings to prevent that.
