Boring, very boring. Not to discourage you from doing more work, but I found the gameplay dull and repetitive. the engine is interesting, but nothing that creative. Reminds me of that old cannon shooting game that came with Windows 95 or something. Also, wouldn't the cannon balls destroy the jewels?
Reviews for "Jewel Mining"
It's functional - I'll give you that. It has a jazz background. I happen to love jazz, but in this case, it's not appropriate background ambience. There is no background story. That's a minus, because you need some kind of emotional motivation to drag someone into the game. There is no ongoing goal, there is no player progression ("power-ups", if you will), and there is no real incentive to keep playing.
In effect, I'd say that this is the lazy attempt of a single game-maker to produce a simple physics engine, with some music and mediocre artistry thrown in for flavor. You really need more peripherals to the whole thing, if you're going to be considered a serious game designer.
I'd advise you to get together with a few peers, and discuss what makes a good game, before you submit this for review.
Now... I'm not the end-all, but I consider myself a fair critic. If you have any questions, comments, or rebuttals, I'd be happy to accept them.
That doesn't work for me.It's not worth it unless you are a completely desperate gamer.
