This used to be one of my all time favorite games. Got 4150 points in my first go there. Played really well and can't wait to see it running as a full time comp.
If I had the skills to do it I have wanted for the past year to build an app with about 20 of these old school games. Ad revenue plus micro payments create a prize pool and users compete for high scores in the different categories such as timed, leveled and skill play. You get so many lives per day but can buy more and a few potions to try and get your highest score every day, week month for steem or DEC prizes.
Apps like that have far more potential to bring in a million users when you can compete for prizes for free if you want or for micro payments if you want a bigger shot at it. Simple but entertaining games that you can play at any time. Those are the ones like candy crush and angry birds that gained big followings as they are so addictive to try and do better.
I would also add a 20% discount to in game items for purchases in STEEM rather than paypal as it gives people incentive to buy some steem to use in the game and you can set up a market for items, skins add-ons ect.
Unfortunately I have no coding skills but would love to see it built at some stage.
Hopefully you can keep developing rada quest and maybe more in the future. We need more apps for the STEEM apps for the phones as that is where everybody spends their time now. Very few actually use computers to go online so the money is where the people are.
Thank you very much for your comment and for your interesting ideas. You'll be glad to know that some of them are on my road map. And I'm open to more ideas, of course.
