I'd say it's a 5 star.  I think the game could be amazing and it seems as though a lot of passion is going into the game. 
One thing that ticks me a small bit though is not being able to set movements to WASD. I know. It's petty, but im running on a 60% mechanical keyboard. Which means I have to hold the FN key to use my arrow keys which means I can't jump while moving. Overall though, I great start to what could be an absolutely amazing game! Keep up the good work and I can't wait to see future updates!!!
