This is a fun defense game! I like the combination of shooting arrows and building defenses; it reminds me of the games Orcs Must Die and Dungeon Defenders. The sprites look amazing, and the other existing assets you used match the aesthetic really well. The gameplay is also solid, though I must admit that I expected the arrows to be affected by gravity instead of flying straight (I think it would be a neat addition if you choose to develop the game further!).
