Nice idea, but very hard (at least for me). :D

Liked the clean art, thought that the other shapes didn't really help me much?

Well done!

Pretty cool game, not sure what the triangle did but the switch between moving red and bouncing blue is a cool one. Would have been pretty neat with some varied up terrain, because you can mostly just go with red until your inevitable doom at the hands of the insanely fast wall.

Is a bit hard at first. But when you get the hang of it is pretty fun! . I didn't figure out what the triangle shape did thought. Overall well done

Took me a while to figure out that switching from a jumping red to a bouncing blue mid-air is how you make high-jumps, but once I did I was able to get up to a high score of 407. Y'know, after some practice.

My main criticism is how much speed you lose on slopes, and the fact that I couldn't figure out what the triangle's for. This was pretty well done aside from all that, but my scores felt like they depended more on luck re: what kinds of obstacles show up than anything else.

There's a lot you can do with this, though.

Remove the triangle form, fix the red block so it has the same horizontal speed on all slopes, fix the blue block so it gains even more bounce per landing, and reduce the red block's jump-height, and set some mine-like obstacles that float in the air? You'd have a game about setting up difficult high jumps as the red block without running out of time or accidentally killing yourself with the blue block's bounces.

But really, you can keep it mostly the way it is and improve on the obstacle generation, and you'd have a viable game there, too.

New high score: 462! Anyway, I like the idea of having to shape-shift mid-air and use the shapes together that way. You should think about fleshing this one out! Get a nice post-LD going.

I got 642 pretty easily.
I didn't find a reason to shapeshift, some music would be nice, and a score counter.
I liked the look of it.
also, it's too late now, but next jam, remember to remove the .pdb files before release.
