This was more fun than i had expected haha!
Its very simple and nice, i feel the only problems are with the grenades, especially when the player throws them, they should explode on impact because they usually just fall off the platforms, but not the enemy ones, its fun bouncing them back to the enemy. Also the background could be more colorfull and varied.
And for Historically Accurate points it falters a little bit :)
But overall, its a nice little game. Congrats!
