Incredible game, no flaws! And when I was nearly disappointed with the lack of abilities, I found the secret one (despite not being THAT crazy mofo power), which made me vote from 4.5 to 5.
Now, go get some good pals to help make a sequel, or second version, with upgrades, more abilities, char classes, you know, the concept is awesome, just needs more details to make this casual gift into a true relic.
Epic hint: Beyond the monster door lies the true spirit of a warrior. But you should let the flames of a master guide you to it. Only then you will unleash your power.
