Hi! Thanks for replying! I'm happy to get your Wiser feedback xD
I love how much goof feedback we got regarding movement and combat, thanks very much for sharing your thoughts on it!
About the boss, yes, its hard and yes it's frustrating to go back all the way, I completely agree. I like your powerup approach, but another solution that has been talked about is checkpoints, which we will definitely put in future versions!
Again, thanks very much for your feedback and for playing!
