Thanks for playing. There are two hit fx for the player. One is missable because its not prominent enough. Instead of the white flash in the sprite, I just changed its alpha back and forth for the duration of the invincibility frames. Theres also a sound effect when the player gets hurt. I do agree that I should have made a hit flash sprite rather than animate its change in transparency. I'm just surprised that you didn't catch sound. Do you think it was due to having too many sounds happening at once? Audio is on the list of many things to improve/learn.
I'm glad you liked the music choices. I was worried about the main gameplay music. I wasn't completely sold on it in comparison to the rest of the music which i did like. I was surprised I found those assets. Maps I've managed to include in every MVM entry. I've been trying to find a way to streamline the current process, but I think this was the best one yet.
