Thanks a lot. You helped me to improve my game. Now you can download it with the new improvements you recommende
Nice the WebGL build definitely makes it easier to play the game.
A few other things you could improve as well would be trying to align the enemy to a grid like the player as well. Or make the player to be able to move freely on your playing field.
There are also some enemies that are stacked on top of each other would be nice if there was some way to fix that (You could for Example always spawn enemies in waves nearly a whole line with a gap between them), because right now sometimes you don't really have to move because you get really lucky or you can't win because you got unlucky.
Still a really great game tough and really well done that you implemented my last ideas/improvements so fast the last time :D.
