Its not too early for a WIP! It is literally a work in progress, so by all means show it off! If you post regular updates, even if they are small updates on textures, models, code etc, people wont mind, and if they do, they can really stick it, because you have succesfully posted a WIP.
It looks good, and I like how you didnt just stop at the first screenie, you actually moved ahead and made it better. Also, you posted an alpha, which is possibly the nicest thing you could have done!
I hope you develop this further!
You using deled for the level? Obviously there are physics involved too. How do you habdle collision?
