Initially you had to fight the ogre for flowers to give to the princess, but I thought that a little too violent, that's why I changed it to a riddle contest. A little simple I know, but I'd rather stick to my morals.
Simple but I found it useful. The most useful thing that could improve it would be to have a sort feature. There are a lot of terrible games out there and I'd like to get a random game from 3-5 star games than get several games I ended up rating 1 star in a row. But now it delivers all that it promises and I can't find fault with that.
I'm not going to lie, this wasn't the game for me. I was bored midway through the first level. With that said, Mario is an easy target for terrible developers who just want to churn out quantity over quality. This is by far and away the best Mario defense game I've played on here. It's not the perfect game but good job.
I wasn't trying to be antagonistic but really? If you read the comments for this game, why don't read the comments posted on the game you just tried to pass on as an achievement? I had the bad luck to upload my second game during Thanksgiving, I'm thankful it even saw 80 views that day. If you want a more accurate way to compare games, look at the scores. My first attempt at making a game was amateurish and plagued with problems that are 100% my fault but it still scored half and again what your "Melt the Ice" did. Another word of advice, delete that game and pretend it never existed.
I don't care about graphics (just look at my games) but you really could have done much more. It's almost always better to practice restraint before uploading and add more content.
I actually went ahead and made another game taking a look at how it can be difficult to create. Check it out, http://www.kongregate.com/games/ausohj/my-mistake
I got out but this time I'm this time going to rate this time a 1 for your mistake ridden game this time. The math is wrong for the code, you have to put an 8 where the 0 is.
Actually one of my games "Melt the Ice" has more plays than all of your games combined so... I win
