Okay.
There are a frickin TON of things wrong with this game. Here is a list.
1. Sometimes you get a black screen when you die. I have to reload the page to keep playing.
Which is really annoying when you're trying to get the medals. And I am pretty sure that this is NOT an issue with Newgrounds.
2. It's the same three blocks OVER AND OVER AND OVER. You couldn't take an hour or so to actually put some detail into the platforms instead of focusing on the background?
3. I got squashed against the side of the screen several times just because I was too far to the left and would have made the jump if the screen didn't scroll so fast. This is VERY infuriating.
4. The shop items cost WAY too much. This is a blatantly obvious case of fake longevity.
5. The Pitty #2 skin. IT DOESN'T DO SQUAT. It doesn't add ANYTHING to your score, it just makes you go faster at the beginning. In the shop it is worded so it sounds like it would add to your score, but that is a bunch of misleading junk.
6. The Pitty#4 and Millionaire medals ALWAYS unlock at the same time. So there is NO use for the last skin.
7. Eventually the repeating music makes me want to rip my ears off. IT'S SO ANNOYING!
8. The character doesn't change AT ALL. You could at least have another sprite for him.
9. It is VERY obvious that almost NO beta testing went into this game. If so, than it would be a LOT better.
10. The only reason I keep playing this game is for the medals, and even then it is STILL boring.
Overall, it is a nice idea, but the execution is so bad that it's not even worth it. Next time, please test the game more, put more detail into the art, and actually make the upgrades more effective and easier to obtain. Do that and you might have a winner.
