Ok so.... I don't want to be negative because it seems you put a good amount of effort into the game. And the art is nice and the idea could be fun but unfortunately:

-It's too repetitive, the gameplay for me was just doing circles with my mouse. -the progress is WAAAAAAY too slow, coins are dropped very scarcely and the upgrade to the drop is a tiny number. -the music also gets a bit repetitive, since it's too "chiming" (sorry, I don't know how to describe it) it becomes a bit annoying after a while, paired with the repetitive gameplay. -controls are super weird, no matter where you point at you'll always move forward which sometimes will make you collide with an enemy by accident and lose health. There's a reason why these kind of games use wasd "AND" mouse instead of wasd "OR" mouse. One is for movement and the other for aiming/attacking. When it comes to controls I always recommend developers to study controls on similar games and not trying to change the way most people play, it's like going against the current. -I don't think there's a way to recover health? so if you get hurt by an enemy that's it? -I don't know why it's tagged as "Idle", it's not idle at all, it's full active incremental unless I'm missing something. -the game is too easy. To access the rooms I had to let myself die, otherwise I think I could have been playing the same level for like 40 minutes without dying. As I said, you just move the mouse in circles and you're pretty much done.

I had to agree with the other user, trying to be constructive and all I have to say that unfortunately the game is not really fun, it's a bit repetitive, and weird to play. I'd go into full WASD+mouse, add some more action/powerups and stuff and try to see what games like Brotato (or similar games) did right to see if you can improve the gameplay.

Hope it helps
