Hello ! Well I played two games and survived each time, collecting something like 15 and 23 scraps.
For the moment the ability to fire is useless since I can easily dodge every obstacle.
I didn't even think about trying the other weapon actually, and mainly because it's easier to avoid the enemies than killing them.
And about future features, the choice depends on what you expect this game to become.
For the moment I think games are really short and you could increase the difficulty over time.
Finally that was fun and easy but too short and empty.
