That was a really great game. It was the right decision to make the arrows pass through. That way, the shots had to be smart. While the enemy AI is simple, the enemy detection light not passing through the Stones was something that could have taken a lot of time. This is a Jam game and the time constraints are obvious. If you choose to move further, I think the things to improve would be adding some ambient noise in BG, a little smarter AI with different types of enemies, different types of arrows, and a little better animation. I know you could have already got such advice from people before me and maybe you already knew what to improve. But, for me, What you accomplished in this game jam was amazing and it was polished to a great extent. Thanks for this game! It's always fun to play something that's polished this much.
Please consider playing and rating my game as well. I would really appreciate it. Thanks!!!
