Funny enough, I actually did make and post another very quick vampire survivor like game.
About the game speed, I usually have a habit of making it on the faster side, as I don't have enough skill or time to make more complex mechanics, graphics, or sound. So I make the gameplay fast and try to make it somewhat engaging to distract from that.
I personally really don't think there is too much happening, the objective is rather simple, if it got too slow it would be void of challenge.
But thanks for the feedback.
