This is a good start. The jump is way too slow, but it is exploitable, resulting in a giga jump. The enemies are fast but it's easy to find their weaknesses. The tunnel under the map is a bit narrow and the player can stuck in it, but at least not permanently. The props are nice to have, some pick ups, and destructible/movable boxes, weapons etc would make them even better. The boss looks cool, and with the tunnel it's killable at least.
After I destroyed every robot and explored the whole map with the super jump I missed only a nice victory scene.
