This is an inherently innovative idea for a game and pairs well as a rage-based physics game not too unlike titles such as Getting Over It. Like every game of its kind, mastering the fidgety physics and trying not to lose it all is so, so addictive! The pogo mechanic works well and is sufficiently useful but unpredictable, with the physics tested at every turn by craggy steps and drops. I love though that the core mechanic isn't tipping over or anything, but the jangly keys in your superimposed pocket. Nicely adds an extra layer of paying attention to what's going on. I really appreciate the checkpoints here...
For constructive feedback - not much! This is wonderfully polished and animated, and the janky physics is the point - right down to the fun multi-layered miner's sprite. I guess one thing that did take getting some use to is that the bandwidth for what lies between a decent bunny-hop and not springing wildly and losing everything is narrower than I thought, which made it a little easier to gauge. But still not too easy or hard. Wish I had more things to put in my pocket as the game progressed!
Great work! I had a lot of fun playing this.
