Not a bad idea, just need work on execution. For starters, don't have an annoying icon that takes up 25% of the screen pop up to warn you about something that A.) you have no control over and B.) you can plainly observe for yourself. I can understand having it there, but maybe just as small, single line of flashing text or something (I do realize there is an option to NOT take her along, but even so there is not reason for it to be so distractingly large) . Also, either make the shop a fully accessible shop, or just change it to power ups you get by progressing through the game. It's annoying that it shows all the options you have "available" but won't let you purchase them even though you have enough money. It's already set up as a progress linked unlock system (with the whole skulls requirement) so just finish it as such instead of giving us false options. I would also suggest cleaning up the homing rockets flight path a bit. Not a bad idea, just needs a little polish.
