Game looks interesting, but is really buggy. Tho I don't know what is bug and what is intended, so I'll just list things which doesn't work good as for me:

• Player controls: it feels really strange tbh. Like when in some games you get bad bonus which turn your controls to be opposite, and when you press right you actually going left. Minigame one is more interesting, but main character controls...

• It's hard to understand that minigame panels is interactable, I wouldn't know it if not read description. They're just very similar to background. If they were placed other side, so that player could see visible bright blue screen, it would be much better.

• Minigame is unintuitive too. I got that top numbers mean how many enemies left, but why bottom one goes from -100, then after damage it goes from -10000 to 0? I guess it's just non-initialized health value.

• Idk if there's more, but I couldn't pass past blue circle on ground, there's door which I couldn't open.

Also, bullets look strange(debug scale?), big enemies haven't health bar, but has same health as small one, which feels wrong. Well, I wonder is there more of game past that door, but I can't go there. And yes, in free assets note you say that you used some music, but I couldn't hear any, so I guess it's bug too.
