Pretty nice precision platformer, very impressive for 4 days!
As stated in other reviews, it's difficult to tell at times, what's important, and what's there just for the sake of it. Other than this small drawback, the art is very nice and crisp, pulchritudinous even.
The difficulty could be adjusted in my opinion though, making the game challenging, but easy enough for the casual player is no small feat after all.
I myself specifically struggled at these 2 bolts, I couldn't find out how to get to them no matter how hard I tried.
Also another thing which struck a chord, although I don't know if it's the web versions fault or whatnot, was that the diagonal throws were extremely hard to pull off, I only learned to make downward diagonal throws by doing some very weird fighting game inputs, as holding them down simply didn't work.
But other than that I liked the game very much, I spent quite a while messing around, long enough for the music to cutoff. (nvm I probably tabbed out)
Also bonus points for using a less popular engine, framework?
Very nicely done!
