Well this is certainly a lot faster than the old version with blocks that I originally played! The walls no longer having "health" makes a world of a difference in making progression less painful and the upgrades also seem to be more efficient now (or maybe that's just the fast progression in general). I was able to turn my guy into a jackhammer pretty quickly.
That said, I had all upgrades except inventory maxed out in this version before I even found the second object, so maybe it's a bit too fast now, which also makes the diamonds pointless after the first few minutes. Maybe if there was something else to work towards?
