I'm not able to get the Neapolitan bonus. I tried Chocolate, Strawberry, and Vanilla, but that order didn't work. I also have a Strawberry surrounded by Vanilla on the left and Chocolate on the right, but that is also not working.
Controls are counter-intuitive and not very user friendly. Make the dog only turn around instead of moving forward when a direction is pressed, and allow for the buttons to be remapped and you'll have something worth talking about.
One thing that I noticed (besides the buzz sound at the end of the level even when the game is muted) is that the support towers don't show their effects on towers that are in range after they upgrade that weren't in range before the upgrade. They only show this difference after another tower has been placed.
If you hit one lightbulb before the other turns off, then the seond one will not take effect. Try to fix that. Also, don't make your main menu automatically open up a new tab, that's just annoying.
