I am viNetti on there (no idea where I got that name from).
It's hard to not just jump in and defend Construct even though it has it's share of issues. Clickteam needs more competition regardless. They're slow.
As for the demo itself ... it really is a copy. It's one thing to make a game shooting ghosts, but they approached it by making everything look/feel as close to Ashley's demo as they could using an inferior set of effects.
Long story short (is it too late for that?), Ashley +1.
