Cool game! Though it does get a bit boring after a while. I could think of couple of reasons that I think contributes to this: The area being too big, the enemies being slower than you, and the fact that your bullets travel farther and for much longer than your enemies, all of this encourages the player (or at least me) to just, run away and snipe your opponents from a safe place, which gets stale after a while. I think making the area smaller, your bullets' distance shorter, and maybe adding some powerups that only appears when you kill an enemy could make it a bit more engaging to the player (or, again, at least me). Still tho, that's a really good looking game! I love the entirety of the presentation. Nice work!
