Has been very boring as you play a level upgrade your stuff and play the next level without any problems. Nothing to think about just shoot and you'll pass them all.
Nice idea but the controls are not precise enough. Its annoying if a block is moved too far and all other blocks are also moved unwanted. The achievements should differ for the certain levels and they should be visible immediately. If you have to look for what the achievements are like time is already gone. 2/5
A Gemcraft clone. Would be nice if you could move the hero. More information about updates/costs are definitely needed. Also what are the different types of "gems" doing?
