I love the PS2 type of graphics. This brought me back to the Tomb Raider vibe. Well done!
All the mechanics are well executed and the fact you can build momentum is always great as a feature! I don't know if you are familiar with the game Team Fortress 2, but the level design reminded me some rocketjump maps. I love that you exploit the mechanics and all the combinations of them. Sprint & grapple or sprint & boost are so satisfying.
This game definitely has potential, keep working on that! Great job!
