finally was able to play this fun game. loved the art!

Really neat idea. I think the fall damage on the blue artifact is a bit too much. 

The idea is quite interesting, but it's very hard to control the game.

Interesting game, though a bit hard to play in it's current state. In particular, I think the way the artifacts you aren't currently using get passively attracted to the current artifact makes it all feel a little out of control. I like the way the color-scheme changes to indicate which artifact is selected, that really helps. I also like that there are multiple pieces of music, but think perhaps a single longer piece could help - on the first level, it just got repetitive a little too fast because it was such a short loop.

All that said, nice. Keep it up.

A bit late for that, but some friends asked:
The platform at the first level will only go down when the 'Yeallow Battery' touches it.
Yes, only the 'blue mug' can get hurt
The level changes only when all the artifacts are in the end of the current level

I would do an in-game change and all, but since the Jam is still running, I can't
So maybe I'll mess with this project in the near future

Very cool and original idea, great work! I'd love if you tried my game too btw (:

Very nice concept, the idea is really original! It is hard to play tho, but I very much like it congrats on the game and finishing it :)
