Well, I hope you can withstand some criticism:

• Release your source code. Irrlicht engine is cross-platform, but of course one cannot compile it on other platforms than you are using without access to the source. Other coders can also give you hints how to improve your programm or even join your project that way. For releasing your code I'd strongly suggest you to use a version control system (such as git, which is my favorite one), which allows you and others to keep track of your project's development and to get the latest versions of your code even between official releases. An alternative would be just to release a source code version of each official release.
• Improve your sourceforge site. Add at least basic information about your project (the genre, game design etc.) and some eye-candy (screenshots, WIP's etc.). Why should you improve it? To make it more attractive. At the moment, most people visting your site by accident will leave it and probably never return.
• Add a license/copying declaration to your project. This is very important for any project you want to make public.
• Get rid of the IrrKlang and ikpMP3 dependencies. IrrKlang is free to use for noncommercial projects only, and therefore is contrary to any free/libre software license. It's also contrary to sourceforge's Terms of Use.
• Don't use stuff which is trademarked by anyone, such as the Coca Cola soda machine or the name LEGO (call it bricks instead). Not even as placeholder art.

I hope this was not too much of criticism ;-)

Not hosting the source on SourceForge is probably against the terms of use of SourceForge.
