Hey, thanks for playing and for the feedback! I completely agree with the issue of attack repetition and lack of variation, it's certainly the least polished aspect of the game. In reality, it went through a lot of different iterations during the jam time and I'm not happy with how it ended up, I'm absolutely going to be refactoring it for an after-jam version to make it more exciting and varied. There are a lot of attack patterns *in* the game, classic bullet hell circle patterns, sine waves, and another variation of the spear attack that isn't used because it caused so many glitched with the generation despite being available.
I'm planning on making more handcrafted scenarios mixed in with random elements to keep it exciting, and I'm wanting to add some of the other things you pointed out, (Highscores, a boss battle, etc!) And making more floors that are like the insane ones shown on Twitter lol. Again, thanks for the constructive criticism, and I hope that when the game is patched it'll live up to these expectations!
