Here is my contribution, I guess I am in for the raffle. Feedback shortly below.
This game was an improvement to El Dorado. The graphics are much smoother and faster to use. One annoying thing is that spinning manually after each win requires the player either to wait or click twice for a faster run. Altogether it is a simple game to play, nothing special in it really, good for fast consumption with the bonus buy. My bonus buys (10-15 in total) were never above the price, the win below is from normal play, therefore I would really not buy bonuses on this one later.
Pros:
Simple execution of a game and fast to play with sound graphics, at least to me
For a player it is easy to learn what to seek and how the game pays
Cons:
Nothing really special in this game, unfortunately it will not necessarily have a long life-span amongst players. I would not recommend joining the "highest x-win" contest with Netent or BTG. Games can be simple and they can deliver smaller maxwins and still be entertaining.
Free spins feature offers always too many deadspins, I guess I had 30 bonuses so far and usually 5 or more are deadspins. Quite high volatility could be amended down due to relatively small max win.
