Well, I played your game and it was mildly enjoyable.
The programming was solid. Couldn't find a glitch, besides an invisible wall in the basement. The music was good the graphics were really nice. And the Giant goomba was a great boss fight, even its sneer at all those mario games was great.
You might ask if you like everything, then why is it mildly enjoyable? Well there is one big flaw in your game. Everytime an enemy died the game went into slowmotion speed and you got a big splatter on the screen. The first time I watched it, it was like: "!@#$%, this is wicked!!!". The second and the third time were: "Nice!!", fourth and fifth: "Hmmm, is this gonna happen every time I kill a goddamn goomba?" and after about ten times: "Damn this is frustrating! Am I gonna continue playing?" And after the 20th and each consecutive kill: "Please let this end soon."
The slowmotion and the big splatter really are breaking the gaming pace and the illusion of being with the character. And that destroys a lot of fun. If you kept this to a bonus for an outstanding performance like killing 10 goomba's without landing on the ground, it would be a great addition. Now it is more of a burden. And especially a burden with the boss fight.
Without that major flaw, this game could have been easily one of the best fan-games I have ever played. I hope you fix this for the next episode, I will be waiting patiently. But this one rates as a small 6 out of 10.
Number of enemies killed: 137
