Bugs:
If you encounter an enemy just as you enter the map exit tile, you will skip the encounter, but end up frozen on the next map over. Bricks Autosave
Pressing ESC during dialogue with either NPCs with paper dolls causes a very strange visual glitch.
The supplies aren't actually taken out of the player's inventory after completing the quest for Fox.
General thoughts:
The Powershot isn't really that worthwhile right now, it does...8-9 damage to the base pistol's 8-7. Though I suspect balance wasn't the focus for this.
I'm not quite sure how you'll approach NPC romance/scenes, but playing through the patch made me think there's a missed opportunity with not being able to report back to Fox after getting the Scrapyard key. I thought it would be interested if once the topic of "the boss"/El Shark gets brought up and the player is given a choice of either lying and saying they beat up/killed them (the latter would be funny if Fox could encounter El Shark later on, and comment on it if you choose this), or tell Fox the truth. Fox's reaction to the truth I'm kinda clueless on, but I thought a simple comfort/sympathetic hug/kiss would fit her. I did think of a reaction where she's really concerned, and asks if she did anything beyond kissing the player, which upon finding out they didn't, she acts excited for a second, then stops herself and goes back to being concerned/sympathetic, but still clearly happy that El Shark didn't have "actual" sex with the player. I think you know Fox's character better than me, so I'll leave their reaction up to you. Speaking of Fox, I think there's something up with her tail sprite, as it looks nothing like the Fox tail of the player race.
Still gotta make new face sprites but I'll probably add more little scenes like this! This will be a nighttime event.
