Thanks guys, glad you liked it <img src="smileys/smiley1.gif" border="0" align="middle" />
I exported to Phonegap from Construct 2, then used Phonegap's build page (https://build.phonegap.com/) to build the game. I only had to make some adjustments to the screen size since Android has multiples resolutions and aspect ratios.
To properly publish in Google Play you need a publisher account with google (US$ 25 last time I checked), then you can publish the game like any Android App. The only difference is on the signing process, it has one extra step when using Phonegap to build because it adds a debug key, so you have to remove it first, and that's it.
