Incredibly buggy
First of all, the controls were very glitchy. The character sprite would repeatedly walk in directions you weren't pressing, and this caused me to die on level 27 when it decided to walk me straight into the mob of enemies I was backing away from. But, aside from that, I couldn't even fix the barricades. Every time I did, the game kicked into fullscreen mode. The problem is it wouldn't let me move at all in fullscreen mode.
The game was fun overall, except for the fact that I couldn't control my character half the time, which ultimately led to my loss. Also I entirely missed out on what seemed to be a central gameplay mechanic? Kind of disappointing.
