I feel like this is an interesting concept, with some potential but it needs more visual and audio feedback. As a first time player, we have a short dialog which is nice to explain that we’ll only control the sliders, but then, we don’t really see what the sliders are doing. Also, I think the game is too slow, which makes it more confusing because you’re unsure about the slider’s effect.
Make the bullets bigger, and find a way to show the effect of the slider. Maybe add some audio.
Congrats for your entry!
