IntroComp specifically says that entering there disqualifies the finished game from IFComp, so…quite possibly? And the second and third question on the IFComp FAQ about Entering Games say that as well (emphasis mine)…
However, if the game was available on the public internet, where anyone could find and play it, then the IFComp considers that a release – even if the game wasn’t finished yet. This would be the case if, for example, you linked to the game from a public forum.
If you’ve already shown the work, whether in current or earlier form, in other festivals or competitions, then IFComp considers it an already-released work and therefore disqualified from entry.
