Lots of great ideas in this game ! I like the choice between 2 weapons, it give us more possibilities fore gameplay. It was hard for me at the beginning with my AZERTY keyboard but the arrows did the works ! Nice work for particule effects and the slash effect of sword! Maybe have more pattern for ennemies can be good for futur improvements :) 

Liked the artistical approach and general idea behind it. A few things I can suggest: most of the time the sapling was in my way x). I think the combat could be smoother if we couldn't collide with the sapling and just go over it. I also noticed it seems like only the tip of the sword deals damage? It was a bit weird at first but ended being used to it (might be a skill issue). Overall, a nice little game.

Interesting idea with alright execution. The combat could have been more intense if the player speed and the sword and bow were faster.

However, I think the story is far more compelling than the game and could be expanded into something bigger. Maybe the astronaut designed these robots to protect him, and they all calculate he's safer on his ship than on Earth, leaving the astronaut to decide whether to trust the science or his basic human instincts (or are they one and the same?). It's a simple sci-fi setup you could go really deep with.

Anyway, good job! Make more games :)
