I'll try not to make a habit of making iOS Pay-For apps the "Weekend Retreat" thing, but there's something to be said for having decent iOS games that charge you upfront, rather than slamming adverts into your gameplay, and IAPs all over the damn place..
So.. Yeah.. If a game's good, it's good!!

This weekend's game of choice is a nice and simple action puzzle game.
Droidscape:Basilica sees you having to drag a little robot through an arena, to get him out the exit, whilst collecting the goody items and dodging the baddies.
The difference, however, is that you must play each level TWICE.



The first time, you drag your robot on through the level, guide him to all the pickups, open the doors, and reach the exit.
During this phase, the enemy are stationary, and cannot harm you. You can see where they are, and the paths they will take, but they cannot hurt you.

Once you've got to the exit, the level begins again, only this time the rules are different.
For starters, all the bad guys are going about their business, and ready to attack and kill you.
Second of all, you've lost most of the control of your droid. Now, instead of dragging him about, he'll, instead, follow the same path as the last attempt.
Your only control over this, is a small "Speed" slider, at the bottom of the screen.
Using only speed, you must guide the droid through the arena, avoiding all the enemy, and getting safely to the exit.

It's quite a fun little mechanic, and one which I'm slightly annoyed that I hadn't come up with myself.. grrr!!!

Thanks to @GnomesLair for the pointer.
