Answer is simple: maemo -> no return on any investment, hobby project at best. Android -> be it ad supported version, or paid app = some return. While map editing is not possible, it should be community that came up with GUI editor for the waves (as easy as vi/joe/mc->f4/ed/leafpad....... script) to make it harder. We should be grateful for a maemo release, not a whiny bunch: but you promised!!! We can't use our own tools where we can.

EDIT: sorry Estel if it sounded harsh or aggressive, but really, making the game harder is just a matter of editing a few files, so no need to restrict yourself, or nagging the dev, just go into /opt/DefGear-maemo/rbase/common/levels and go wild
