Mazinator [check out the free version]

Hey guys, we just launched this game, so I would like to ask you few questions, as long as this is our first bigger project (really huge expectations - covering half of our apartment rent for one month, or at least some beer. or a few people just enjoying the game, w/e).
Right now, we have a paid full version on the market and a free demo version with 5 levels. I was wondering, if it wouldn't be better to make a free full version, but with ads. What do you prefer?
Thanks
Anyway, you can download the free version (as a new member i can't submit external links, so just search Mazinator Free on google play) and if you like it, perhaps purchase the full version with more levels.

A little update for everyone who downloaded the free version and everyone else as well: we decided to enable all 32 levels in the free version, so now it is basically the same as paid version, except it has ads.
