I really liked the game, reminded me of the radar map in Metal Gear Solid 2. For everyone complaining about not being able to kill the guards, you should add a bonus round. After you complete the game the normal way, you go back through the levels again with the ability to kill the guards, but with the catch that any alert (including discovering a dead body) = automatic failure.
Original concept, I like it a lot. Some constructive criticism: I agree that touching the border should kill smiley. I don't think you need the gravity change ability, you could make more challenging levels without it. There is also too much "ink" in the drawing pen. You can pass most of the levels by drawing a path that encloses smiley with the red square and doesn't let him bounce in any other direction. Also, you should make it so you can't draw over the top of the black and purple lines.
Not my type of game, but I gave it 4 out 5 anyway for being an original take on a side scroller. I really like the die and take over another ship concept.
Cool game, but too short. Needs some more units like bombers for escort missions. Also some ground targets/flak cannons would be cool. Would also love to see a naval and/or space game based on this game engine. Still 5 stars from me.
The game is pretty good, but the movement phase is painfully slow. Also found a bug. My Vikings charged and just kept going right off the screen.... game is stuck now waiting for them to finish their never ending march.
