Hey, Flan from the stream here.
I've been thinking about your game. If you were to expand it, I would like to see that the levels, once you get good at them, can be played without stopping much. Or maybe stopping in specific traps that, if you play all in one go, at optimal speed, sinchronizes the silence with the wait.
If any of that made sense, I'd like to see if you expand this. I like rhythm games.
I'm sure you know Geometry Dash, or games similar to that one. If you play one of those, you will see that there's a lot of sync with what happens in the screen and the input the player presses. If you were to find a way of creating that effect while having the current input scheme, I think you'd have an interesting original idea there.
