Hey Kurikaeshi, thanks for playing.
I think I've now fixed the crashes with combat and completing the level. Regarding the pathfinding issues, I'll add that to my todos.
I used a very nice tool called FireEmblemCharacterCreator to kit bash the FE GBA sprites. They are indeed placeholders, I find it a lot easier to work on my games when the placeholders are a bit more high-fidelity. I do quite like the Fire Emblem GBA art style so I'll probably go for something along those lines for the final release. I'd even like to get some sprites that invoke that FE GBA sprite feel, but animated as you might see in a game like Ultima Online for isometric movement.
I made three levels for the demo. The second level gives you command of an army to play around with the formation movement and controls. The third level is a poison swamp that plays a bit more like a Dungeon Siege level with a small party of 3 characters. I was experimenting with some different level designs to get a feel for what was fun and what wasn't.
I'm quite disappointed nobody was able to make it to those levels, as the first level was really just meant to quickly familiarize people with the base mechanics before going into what I considered to be the more interesting mechanics of mass combat and party management...
Oh well, maybe next demo day.
In any case, I appreciate you taking the time to play my game and provide feedback.
