The concept of surviving in the tower is really interesting! It actually felt a bit scary for me, especially with the footsteps and creepy enemies. I think adding some music would really enhance the experience, as just hearing the footsteps got a bit repetitive for me.
I also wanted to mention that I tried hard to beat the game but couldn’t find a score or final level. I think it would be great if there was a bit more challenge or progression as you move through the levels.
