Oh, that’s way better than a cooldown, there’s less room for exploits. But this way you could do the same, but downwards, to avoid risky jumps and slow the descent. I don’t think it’s exactly a bad thing, it’s more a feature than a bug.
Yeah, on several occasions I made a mistake in the position of the block and ended up falling, on the levels with long jumps. Probably could be mitigated by placing the blocks beforehand, but if you mistake the position of only one block, you need to put all of them again…
