Not bad, though you may want to specify in the instructions that the mouse is used for some levels - the instructions sound as though you use the keyboard *only*.
Some kind of audible or visual warning when a larger planet starts to pull you in would be nice - with the small field of view, you often can't tell a planet is pulling you in until you're too close to break free.
I kept playing, thinking to myself that the difficulty sure had dropped suddenly, and when I checked the menu I found that I'd finished the game and the levels had started over. Something saying that I'd reached the final level might be nice.
Fun, but there needs to be some kind of edge-of-screen collision detection for the zombies - on two different levels, I managed to knock one off-screen without killing it, and had to just restart.
Really needs a keyboard shortcut for the potions. When one hand is moving, one hand is firing/attacking, it would be much easier to hit another key to use potions than have to switch to the mouse.
not bad, except for the juicer puzzle at the end - not even so much the puzzle mechanics, as that the cursor size makes it difficult to see which button you're hitting - a zoom in on the puzzle would be nice
unintentionally hilarious - I got 2nd place by just building a bar surrounded by toilets and keeping everyone drunk so they paired up - just like a real bar!
not bad, but could use some kind of minimap for the hunts - I keep killing all but one, and end up roaming over hell's half-acre trying to find the last thing to kill.
