Nice Work. I Really like the idea.

I really loved the idea, made me chuckle once I figured it out. Congratulations :)

(The jumping speed could be a bit more in-sync with running movement)

Good entry with a nice use of the theme! Only little thing, the slow down while jumping was a bit strange to me.

Thanks everyone for the feedback!

Just one question, do you think the jumping and running is really that different? I know they're different (they were programmed this way) but I don't see that much difference. To me, it's almost the same. Maybe because I played it a lot... So it's intersting to get other people's feedback.

Pretty good game. I would have to agree with the previous commentors, the speed while jumping was quite a bit slower and took from the game a bit.

Cool game, love the sound and the graphical style. Fun ot play with a cool idea. Well done!

Really cool idea! First coin I was like "What? Is that all?" Then I got it and I had top play till the end because I wanted to know where this will end.

One thing though: the jumping is kind of too floaty. But the concept is great.

Cool theme subversion! Love the tone of the Game, it really worried why we are not getting those gold coin :))

Holy crap, this game is great. At first I was like, ok, neat twist on the theme, but then I realized you twisted the twist! You win the ludums.

Very fun, my sincerest compliments! I love reading all the text the game throws at me (it's a bit hard, though, especially in the "avoid this" Matrix part).

Love this! I genuinely wondered if that was it when I grabbed the first coin a couple of times before realising the real game led beyond... Jumping was very floaty but I guess I accepted it eventually. Good idea, well executed, really nice little bit of music too.

Great game!

Made me laugh. I like games that mess with the player in a way that makes them feel clever rather than stupid.

Hi everyone, thanks again for the great feedback!

Don't know if you've seem, but I updated the game with some tweaks.
03. Jan 2014 · 00:14 UTC
Wow, this put a smile on my face! The game-player interaction reminded me of portal, very well done indeed! The game flowed very naturally for me, kudos on the writing!

Oww maaaaan, this is so cool. Laughed really hard, once I found out :D

Excellent concept and execution, man! Congratulations!
