I agree with killpower.
A player could have been lucky in an early estate and be unwilling to move, for example he could have found plenty of resource seeds and/or towers. Players should be free to decide to move to next level estate or wait for the successive one. Pressing estate button could show progress bars for all successive estates and ticket to earth.
It would be nice to sell or drop unwanted items (to the trader). In particular, after second world, research items become useless, all researches become immediate.
Hi. Nice game, thanks.
A little bug report and a suggestion:
-After last update I have no more access to the "Call Trader" button, the countdown goes negative and restarts when I open the item tab.
-I think it would be nice to choose at which goal to leave the current planet. Now my goal is 20M but when I left last planet (at 7,5M) I could have easily reached 20M in few minutes. It would be nice to have the possibility to "jump" to a higher level planet or even try to get to Earth from a low level planet.
The idea is nice, but towers should be set to focus fire on first, strongest or weaker unit in range.
Some tracks are really hard to play because units don't always shoot to FIRST enemy (closest to defender base) as it would be expected.
Spells are almost useless.
