Very nicely done. The music, title screen, animations, and backgrounds come together to feel very polished for a 48-hour game. I found it very difficult to build the muscle memory of colors mapping to numbers, so I could only really make progress by memorizing the button presses. That's not my preferred way to play platformers, but definitely works for some players. Maybe if the numbers themselves were displayed on the hazards it would work better for me.

Anyway, great job overall!

Really like the platforming of this game , like the music and the art , the 3rd level was a little overwhelming but i made it in 4-5 dies XD keep it up o/ -Ivory-

Really fun and good looking game!

Definitely one of the best games I have played so far.

I really like the art stlye. Especially the background. The idea is really nice and the levels are designed very well. There is just a small problem with the order of the levels. As already mentioned by EnT_JLR, the jump from level 2 to 3 is madness. The order for the levels should have been only SingleDan and introducing all the colors and then changing to DoubleDan but also decreasing the amount of colors so that the player has time to get used to keeping two Dans alive. You could also think about the rate you are introducing new mechanics. But yeah, that's way too much for a game jam and I didn't rate your game any worse because of that. Just something to keep in mind for the future.

Oh and btw. why is the fourth button using 3 colors? Orange, brown and cyan? Or did I mess something up when clicking around in the options?

One more tip. Maybe keep the button-color-information on screen all the time. Not that big as at the start, so that the player can make a quick peek to see the correct button. Especially at the start or introduction levels.

I hope my feedback helps you.

The game is really entretaining and the idea is extremely well executed. I think that making the difficulty transition smoother could make it more enjoyable because levels 1 & 2 are easy but level 3 is complete madness 

What are Dan's hopes and dreams? What motivates him to just keep going while hoping that forces outside his control will intervene to save him?
