Great game.  I don't read (i.e. i'm bad at reading, i just jumped straight in) so I didn't see that you can zoom out.  Also, if the area is limited you can put a limit to how much the camera moves to the side.  Something like if camera.position.x > ((farthest right pixel - camera.width)/2) -1 = ((farthest right pixel - width)/2) - 1 and then likewise for the left side, upside, and downside.  I couldn't figure out how to get new turrets.  Overall, excellent job creating a tower defense game.

Never thought I would see a tower defense on a Nokia… I mean because of the small screen. But you have managed to do it, I am very impressed! Good job!

Fun take on a 1bit tower defense game! The zoom and indicators really help work around the resolution limitations. Good work

Nicely done! I love how the game is very unique but still a classic tower defense nice job!

Very impressed with how much this accomplishes within the given space! I don't even think I've seen this particular setup for a tower defense in a modern game! Great job.

Very nice! I was a little lost at the beginning. But the game increased great and the waves are very well  managed regarding difficulty! 

Cool game, I liked the tower-defence style mechanics! My playstyle was to pick up most of the ice except for a two-block thick platform under the penguins, which I then covered with turrets. I played till like 10 waves around, probably more. The upgrades system is nice and although I used one particular strategy I can see how people would have varying playstyles for this, which would add to the fun. My turrets demolished all the enemies after I added like 15 of them, which was pretty satisfying because i almost died early on. Good job!
