I could be wrong, but perhaps this should have been posted in with the old thread so that it's easier to compare and critique.
There seem to be some really nice improvements and you've taken on board a great deal of the suggestions made. The lava looks hot (yeah, bad pun) and I think the colours are nice and vibrant--just what I like to see on a mobile game.
For me, the only downside is the size of the player character (the char at the bottom). You might be wanting to give some proportion to the enemies, but it just seems like the player is smaller (I haven't counted pixels, but it looks like they're all the same height in pixels) and therefore less dynamic.
