Woah, thank you for all those bugs! I will make sure they get repaired after the jam. But you basically nailed all the issues. With such a good review is easy to improve!
Is true replayability is poor with this setup and as you mention some new features will help the overall game experience in that sense. I also though on a leader board may push you to try to improve your score.
Anyway your comment is really appreciated railkill!
