I thought your game was very fun, original, and overall excellent. It did really feel like a complete game for the game jam. I really appreciated the humor and the hand drawn graphics. Because of this, I was actually surprised your game didn't make it into the top 5. On stability issues, I was curious to know if I was the only one because I never saw anyone else post or make comments on it here.
I think you are being too harsh on yourself. You certainly know how to make games because AIBOT is an interesting, fun and creative game. On your reasons, any combination of 1, 2 or 3 could be a reason. I'd keep participating in Speedgame challenges and maybe work on improving your game a little and giving it some polish.
