Really cool concept, think moving around as a character hindered the core concept of the tower defence loops. Would have liked just to focus on placement and the different interaction quicker. Completed the first boss.
Also think that activating multiple mines around the green towers is to powerfull (maybe a bug), they had 10 lasers between them at one point and nothing could get past the first long line. Even i couldnt get them to shoot that fast by hammering on them.
I was a bit confused in the beginning. I thought the monsterpath was a wall I couldnt pass and i didnt even know i was playing a tower defense before i tried to hit the green play button. Had to restart when I had refreshed the weapons.
