Hard in a negative way
This is one of those games that is so bad that it needs a whole numbered list to display its problems:
1)----Gameplay----
I like a challenge. And I like hard videogames. The problem here is the following: this game is hard mostly because of its poor, unresponsive and inaccurate controls.
Enemies are poorly programmed and will kill you even after stomped on most of the time (and yes, I mean enemies that you can with a lot of luck kill by stomping).
2)----Graphics----
Again, I like retro-styled games. What I don't enjoy are pseudo-retro styled games that look like something for the Atari 5200 instead of the the NES. The level of detail is very poor and the colors are monotonous.
How about using some bright colors for a change? Would it hurt to make slightly more detailed sprites?
3)----Sound----
I like my games served with a nice side plate of sound effects and music.
Here we don't have music. That's strike one. Strike two? The variety of sound effects is really small. Strike three: Those that are present suck, simply put.
The original Legend of Zelda for example would've killed for 520KB of memory and yet it had more and better sounds than this. How come? I know it's not easy but how about a little effort of your part?
Overall this is just another crap game, the difference being that it uses the medal system to gain exposure, which you then profit off by showing ads every 20 deaths.
If you have the slightest sense of decency make sure this disappears from the games with medals section.
