The maps are really weird. You walk on and over doors.
Respawned Gamers, you should pay attention to the priority of your events. (Bottom left corner of your events) If it says "Below Character" then the player will be able to walk on it. You typically want your doors to be "Same as Character" that way they count as obstructions and the player won't be able to walk on top of them.
I find it weird that the NPC is berating the player for 'playing too many video games.' Know your audience.
It's cool that you're using particle animations to showcase stuff that's happening in events, I like when games do this, very nice. (Like smoke coming out of a chimney) Maybe tone the number of poison bubbles coming off the meteor down a bit though, too much of a good thing can be a bad thing.
The sound effects picked for some of the events are kind of odd. I walk into a building and it sounds like my whole party got poisoned.
The giant open maps are really awful, but some of the paintings on the wall are pretty cool and I like them.
Most of the NPCs will not interact with you and in general there's a big lack of intractability in this game.
You can tell a large portion of the maps were copy/pasted so it feels very cookie cutter and bland. I would recommend making smaller maps with more detail, and don't make all the buildings look the same. Try hard to make them seem different even if you start by copy pasting them. Add details that apply differences so that the player can distinguish them.
It's kind of unclear exactly where to go and what to do, I can't get past the fallen meteor. It one shots me for 2k damage and I deal 0 dmg to it. I'm pretty sure I'm missing something but not sure what I have to do. There are plugins out there that will show a box telling the player what to do, but also you can do this in many ways without a plugin. Like showing a glowing path that changes as the story progresses, using variables or even give the play an item that they can look at to run a common event that changes based on what step they are on. There are many simple solutions you could use.
Make sure to make a thumbnail/art that shows of the title of your game so that people can remember the name of your game. It could be the best game in the world but if you don't market it properly nobody will ever know about it.
The game suffers from many rookie mistakes, but at least you got a project submitted to a game jam and that's not something everyone can say, so great job submitting a game and I'm sure you've got better at using the engine over the course of making it. Keep at it and good luck! :)
