Decided to try out D Lix for the first time, hoping to create a level for the design contest.
So far, I do like the editing interface, but the play level interface I'm not a fan of, particularly the skill icons. When I use fullscreen mode with my laptop's resolution, (It's 1366x768, therefore the buttons are zoomed 1.5x), I still get tiny skill icons that I can't read. May I suggest that each skill should be labelled while playing, whether you hover over it (ideal) or click on it.
Also, I think a black outline around each lix skill would look nice, just like in DOS Lemmings. That might also help making those icons display more clearly.
