I really wanted to like this game but the keyboard controls were just too finicky for me to actually progress further. Once I got to the stack of explosive crates, I couldn't manage to make it underneath the next one before it dropped. That's probably not at all far into the game.
The sounds were okay and the graphics, while good, could be improved with some environmental shading (like the character has). It really came down to the keyboard controls and the fact that no matter how hard I spammed keys, sometimes I just wouldn't get any response out of the guns.
It's definitely worth a play for the movement alone, if you happen to have a controller. Still, well done!
