This game is really really great, but it has some flaws. It's very confusing to get into, it took me about 5 runs before I understood the mechanics. Then when i got it and got a run where i charged my character and became that fire monster it got really cool. But after that it got a bit boring quickly again because it feels like there's not a whole lot to play for.
The art, animations and music are so great. I know it's a very old game but i think it would still be really cool if you'd make a better game using that stuff. Make it more accessible and more stuff to do!
