Definitely a very cool game! For feedback, I definitely agree with others that adding audio will add a lot more to the gameplay and give it a lot more juice. All of the times I died were times when I couldn't hear an enemy sneaking up behind me, so it'd be great to hear them. Even some background whirring/wind rumbling would go a long way. Aside from continuing to polish it, other cool ideas would be adding some new movement mechanics. Maybe like a dash mechanic, or something like that? Just some ideas, but keep up the great work!
