Good little plattfom action game you made there.
The controls feel quite good and i enjoyed jumping around the map (and on the agents especially).
As mentioned before, i would also like to shoot directional at the mouse position. In this case the agents have a significant advantage over the player.
Sadly I hardly ever got a healing item because they spawn a couple of times ouside the map.
The visuals are ok, i think making the objects you can see in the background, realy foreground objects would be nice.
I am not the type of player who likes round based wave shooters, so maybe some little objectives (for examples: pressing buttons in a certain amoung of time) could spice up the gameplay.
Overall good submission! Great job!
