Biggest problem is that the game is too hard — in a bad way. High difficulty is fine; but, as Miyamoto said, if the player loses, it needs to feel like the player's fault.
The dot follows the cursor pretty slowly, so the player dot sometimes crashes even if the mouse dodges an obstacle. The randomness in some levels, like level 13, sometimes made the targets feel impossibly fast and far apart. The game should feel beatable every run-through. Also, my basic Logitech mouse isn't quite accurate enough for such precision work on so small a screen; I shouldn't need to pull out my Razer for a casual game.
Great ideas, though. Simple system, but you do an excellent job pulling in elements from other genres within that framework. I recommend speeding up the player dot and reducing the need for pixel-precision accuracy — some areas are just a couple pixels too tight. As Mark Rosewater said, "You don't need to change much to change everything."
Oh, another thought: it would be nice if the cursor changed for flagging mode. I've accidentally searched when I meant to flag a few times. My own fault, but it should also be easy to make it even clearer. :-)
Excellent game. The left-/right-handed clues could use some additional checks. One game I got a "murderer is right-handed" clue, but all the suspects were right-handed. On the other end of the spectrum, I got an early clue saying the murder was left-handed, which eliminated the FIVE right-handers. I won that one with 40 time left over.
This was a 5-star game before the improvements, but the new control scheme is more intuitive and the new checkpoints are handy. Achievements worked perfectly for me, too.
A couple of times I've beaten the last enemy on the screen between the start of a wave and when the first enemy appears. This means I fight two waves at once without calling early.
Maybe send out the next wave if there are no enemies on the screen AND there are none queued to come out?
The Dragon on floor 10 seems to be glitched. It showed up as having zero HP, and none of the buttons worked except for "Exit."
For those who missed it: you CAN move around with the arrow keys.
Ah; it makes sense for it to be a possessive. In that case it should be a plural possessive as nolafugee said.
@XtyphonX: nolafugee was referring to "I want to fight with alien's" on the title screen, not to the game title itself.
Nice job on the update; gets a 5/5 now. The first version only got a 5/5 ;)
Kudos on the upgrade system. I like being able to respec at no cost, and the battery system neatly avoids the grinding aspect of DvM.
Minor typo: On the main menu, there shouldn't be an apostrophe in "I want to fight with alien's."
I agree with Illucoran that there should be a chip indicator on the level select. You should be able to tell at a glance each level's current state (locked, unbeaten, or beaten) and whether all chips have been collected.
