IF I HAVE A GUN WHY CAN'T I JUST SHOOT MYSELF!
The controls were pretty solid. I never missed a jump and thought it was the game's fault.
I liked the Indiana Jones style invisible bridge. I was bummed that the lava didn't kill me despite all my efforts to get over to it.
The level design was where the game shone best. I think if you made a quick solid game foundation and iterated a bunch of levels you would do really well in the future. It's a shame the gun wasn't finished, but it did make me smile when the bullet just kind of floated away.
Oh the flag dealing damage to the player didn't read well to me. Maybe set the flag on fire or something.
Congrats on the submission.
