Good game!
The difficulty reminds me of the NES (the good old gaming world!). One hit and you're gone. King space's character is actually very F'in cool.
However, there should have been a health bar/status of the enemy. I mean there needs to be some indicator as to how much damage has been inflicted on king space. Moreover, missing out on a storyline and medals.
Nevertheless, a great effort by the author. Looking forward to more amazing projects. Keep it up!
