PENELOPE

Thank you again for playing! I actually watched some of your videos before creating my game, so it was a delight to see you play it! 

Here are some detailed thoughts, with the observations I had while playing and some advice! (spoiler warning)

 * you can remove all those default resources if you're not using them! (except for system2, for some reason. I usually set a blank graphic there in my games). If you're not using any "vehicles" you can also set their graphics to whatever in the System tab, so that they no longer require their own graphic. Other than the vehicles and system2, I don't think RPG Maker checks for the existence of any resources until your game actively tries to use them.

 * Lovely start, with the bridge you can walk over and under right at the beginning! And it makes a sound, too. Now that's an underused mechanic... for good reason, but it makes for a nice touch in moderation. I also like the box being visible but unreachable until you walk a bit more. It's the little things!

 * You could probably set the cliff edge tile to only be blocking on the upper side, so you can walk right up to it.

 * math puzzles! I like it. Surprisingly, I don't think I've ever seen a puzzle like this one in rpg maker.

 * not sure how I feel about the totally nonexistent storyline so far... but maybe I'll soon find out why Penelope never speaks. If that's even the main character's name.

 * the battle first is not much to speak of... but to be honest, I've been working with RM 2k3 for over a decade and I was never able to make good battles in the default battle system, so it's fine. The good thing is that it didn't drag on.

 * So now Mead is not only letting us stay for the night, but embarking with us on a potentially deadly journey. What a guy! Nice to see we're unraveling the mystery of Penelope, but Mead and his little town could use some background too. Maybe I'll find it up ahead!

 * Mead is invisible in battle? That's kinda weird. And why do the dogbeasts drop hot dogs upon defeat? Are the hot dogs in fact made from dog parts in this world? Dubious indeed.

 * The graphics are pretty good despite their simplitity, and only a few things about them bugged me. The water could use a different texture for sure - maybe some lines instead of the dots like the grass has? Also, the bushes have been blending in with the ground and I mistook them for holes. Maybe add a bit of an outline, or make the outer bit brighter.

 * Well, now I can see one reasons for other party members to remain invisible. Would be hard to fit Nessie into the regular-sized battle hero graphics! That was a nice surprise. Speaking of the battle itself, it was difficult but fair - a tricky combination to achieve in default RM2k3 battles!

 * Here's a fun tileset trick - when using auto-tiles (the ones with borders and stuff, like water), hold shift to prevent them from changing! You could use that with the lighthouse, for example, to make it look like it's truly above the water, without water borders surrounding it. In addition, you can also hold shift with right click to copy a specific type of auto-tile! So if you wanted three thin water streams right next to each other instead of one big pond, for example, you can do that too.

 * Defeating the Daytona fish didn't seem to reward me with anything, and I couldn't figure out the significance of 2 and 8 on the wall either. But once I got the other two numbers, I could bruteforce it easy!

 * Oh. It meant that the 2nd one was 8. Okay.

 * I'm kinda doing things backwards, taking on the cityworld after the islandworld. Seems like a good choice though.

 * Yay, exposition! Not sure why it's a random guy on the street delivering it. Could've been a road sign or something. But that works too!

 * An empty, gray room with signs that say PARTY! That sure is promising.

 * The poster closest to the partyhouse didn't change its appearance when I replaced it. Overall, a fun little quest though! 

 * Well, here we go! The explanation, with no stones! But of course, there's more to be understood...

 * Oh, nice. There's RPG Maker on the screen behind, even! As far as simple plots go, this one's real nice.

 * The final battle was a bit of a letdown - the big boss has too much health, too few offensive capabilities! Maybe give them some sort of status effect spell to incapacitate the heroes with? That would make the boss stand out nicely against the other enemies!

 * Also, the ending could be longer too. If just to let the ending song play properly! Maybe just a few scenes of our heroes hanging out together.
