Someone asked for constructive criticism in the Discord so...
The art is very consistent and who doesn't love hitting kids? /s It's a hilarious premise and the art fits it to a tee. But the actual game doesn't do a whole lot to help with that. With the hit bar in the top left of the canvas, my eyes are drawn away from the action, and I'm unable to appreciate the vicerality of the damage I am doing to a fictional child. There is also a lot of deadspace on the bottom of the screen - the upper half feels very cluttered in comparison. A better distribution of the game components might help bring out the art more.
For a simple mechanic, I feel like there is a lot of feedback that is missing. It's good that there is a flash on hit and particles on a... combo, but for a game like this there is no such thing as too subtle. There could be some warning to an incoming pattern change so that the player doesn't miss, and some visual feedback on if an input is a hit or miss (such as a change in the star color, perhaps?) would give some feedback to no-miss runs.
To reward the player for their play, you could probably add in a combo display. The level complete screen could show the time to complete as well as the highest combo reached. Would also make speedrunning easier.
With all that said, I want to reiterate that the premise is utterly hilarious and the art well polished - none of this is what you haven't heard already. And I also do not recommend hitting children in real life.
