The game is quite basic, but it has everything it needs to be called a game, and all of it is done well. The only thing is that the indicator at the top is way too huge and blocks a significant portion of the view. It would probably be better to make it smaller and place it outside the gameplay area. Maybe even make it vertical, so it doesn’t squish the gameplay area vertically.
And a small note on the graphics: on a 240 Hz monitor, the player sprite gets blurry during movement. I’ve run into a similar issue before — I think it’s caused by camera movement smoothing. Though I can’t suggest a proper fix, unfortunately.
