First off, wonderful game. I remember playing this a year ago and thinking it had potential, but now I've finished it and I have to say: that was absolutely great. Good enough to get me to pay for this even though you graciously allow free downloads. The only bad part is finishing the game and realizing that I won't see more misadventures with this crazy crew!
By the way, I know that your attention is focused on Eternum now (definitely going to check that out), but you should consider adding some extra scenes to the end of OiaL that let you talk and "interact" with your girl(s) after the finale. Just as a way of giving closure to the game and leaving the player with a last reward for getting their ending.
In any case, great stuff and I look forward to your next project!
