Hi IGKU,
I've added lots of mechanics including wall running and a grapple hook. I've also added a smash attach which does critical damage when pressing c in air as you suggested. I'm still refining the mechanics and lot's of new enemies and guns have also been created. I just have to do the levels and the story art but it's gonna take some time to finish. I will be releasing a demo next month to get feedback and I hope you stay tuned for that. Thanks for checking in btw.
