That is most definitely NOT a parser-based game. It is a choice-based game, which is exactly what this comp is NOT about. However, you can enter it in IF Comp later in the year, where the majority of games are choice-based games.
The Windows-only aspect is not a problem, but you won't get as many people playing it. In the past, Windows-only games have not been very popular and have not rated very well in IF Comp.
