Music...Awesome

First off, the music was awesome. I absolutely loved the music totally made the game for me. The game is self was also good you just need some improvement on the visuals. Great Job!

Goood

I don't think you should improve the visuals, it would only spoil the atmosphere. I don't really know why I enjoyed this game so much, maybe because it feels so clean, so pure. The death animation of the enemies is just incredible. Cannibals turning into angels. And that huge sun and the clouds you can jump on. I'm not joking. Fix the glitches and finish the game. It's gonna be sooo goood.

Needs serious work

As you know, the grave causes the game to shift your screen around and such, which definitely needs work.
The instructions link didn't work.
The music was, frankly, annoying, and I couldn't find out how to toggle it.
The boomerang was reasonably badly animated (It kept disappearing).
Some soundeffects would be nice (such as when picking up bonuses, killing baddies).
Indy kept walking when he jumped.
The cloud thing was, while a good idea to add, annoying. Perhaps it should stay hidden less long?

Ooooo....

The reeson 4 the big 0 is bcuz it waz a little boring and i died on the 1st level and i dont even no y. I jumped and next thing i no i got a grave on the ground! Mayb its a bug so just want 2 let u no.

Visuals

I would def. work on your visuals, sprite animation that kind of thing. The platforming mechanics aren't bad though. The music is fun, and I like the layout of the menu. You might want to fix the link to the instructions, it didn't work for me.
