I think I quit at level 4. The game lacks a lot of feedback when shooting, receiving damage, or gaining blocks. Once bridge is built, placing it always started from the center or whatever size was the zone, placing the cross here, so the boundaries are actually misleading. Solution I found was to place blocks both on right & left to center it as I wanted.
This being said, the concept fits the theme a lot and overall the game is very much functional. I actually love the block system. I almost feel like it would be better if you didn’t have ennemies to kill and just gather blocks around, and go back & forth to consoles to get blocks back, insisting on the puzzle side of the game.
