The game is ok, but there are a lots things to improve:
1. The boss fight is challenging, has a clear design about their move set, but it shouldn't be totally random. Also need a clear clue how to damage the boss. The "thing?" above the boss is too distracting, and giving user a false goal (I thought I have to break that thing to fall down into boss's head lol).
2. The wall jump is frustated to use, I had a really hard time finishing the chasing act.
But anyway, it is still a solid game! You guys will keep getting better at making game I believe!
