After completing repair jobs you can use money earned for research and development on new inventions. These will allow the player to add more variety to their characters movement and open up more opportunities for manoeuvring throughout the environment.
Examples of inventions:
· Grapple Gun: The grapple can be used on edges of platforms and often is used to get around ledges that are surrounded by higher areas. Its downfall is that certain edges/ materials may not be grappled onto.
Some variants and developments of this item could involve a different grappling head for the gun that would allow it to be shot into certain walls allowing for more variety in its use. as well as something that allows the gun too reel in.
· Jumping boots: The Jump boots just increase the length of your jump and allow you to traverse spots you may not normally cross.
This invention is a bit flawed at the moment as it kind of does a bit of what all the other ones do but I would say adjustments would maybe let you run faster as well so you you can use your momentum to make longer jumps
· Climbing claws: The climbing boots may be used to climb up certain walls and are mean that some ledges that are usually just too high can just be reached.
An improvement to this that you could make to give your character more traversable within the world would to secure yourself to a wall and allow you to jump off from it as at the moment I think of it as a very attacked to the wall sort of item.
· Glider: This will allow you to glide from a higher area across a gap to lower areas.
This one I don't know if I will keep as I feel like the idea of just getting out a glider and flying across the level seems a bit to fictional for what what I'm thinking, as well as that I don't think the levels will that enough verticality for gliding to make sense.
Overall I think these would be good ways to implement in variety and choices for you both when you have finished levels as it means you can upgrade different things as your reward and variety in your way of being able to accomplish levels.
