Thank you for your feedback, we apologize for giving you false hope. The average playtime of all our playtesters was 45min - 1 hour, that's where the estimate comes from. Thank you for giving SAI a go.
Thank you for your response. Keep in mind that QA runs will take longer than in-game play and could make your estimates inaccurate if you use the testing average for playtime estimates on future titles.
Really glad I read TheKingsman's comment before buying your game. It looks really promising, is it still in development or is it finished?
