Kinda want hotkeys for ereaser, some basic elements like water, steel, stone fire (or better 10-15 bind-as-you-wish keys) and a key for pause. Either way, it`s pretty nice sandbox.
The game is a nice timewaster, when you need something not boring but not too time consuming as well. I`d like the unlimited mode when the map grows with time, say, a row of tiles on both axis every 4-5 minutes.
This game was really fun to play, the only complaint is that it could be longer, hope you`ll make a sequel. Also, could you please upload the soundtracks somewhere? Or post a link to a composer`s website or something?
