Thank you for playing the game and for giving the feedback!
Unfortunately I didn't have enough time to work on that for the deadline, but since time is no longer a problem, all the issues regarding balance and lack of clarity when it comes to gameplay will be addressed with the next update/updates.
As for the more than 3 negative points situation, that's a bug as I've included the upgrade node in the random event by mistake (I've thought about having more than 3, but it seemed like it'd be too OP unless there was more than one map the player would progress through; so it might be a thing at some point!). Very glad that you seemingly didn't try to fight 6+ enemies (made possible by the extra upgrades) once you had the points, as it would've bricked the game XDDD
