Hi thanks for playing glad to hear you enjoyed it.
Yes it was made in RPGMaker MV, I used the MV3D plugin that CutieVirus made (https://cutievirus.itch.io/mv3d) for the 3D and forcing the first person perspective.
Also yeah I think if I end up doing more work on the game after the jam it would be worth making it so all the chests have unique items or gold. I remember playing other RPGs and finding it annoying when the item you just spent all your gold on shows up in a chest 5 minutes later so will definitely swap the Tyrant Armour out for something else.
Had a bit of trouble deciding on the encounter rate too, average of 30 steps felt too low but think 15 might be a bit much if you don't already know where to go. Think I have an idea for how I can put the enemy encounters on the map and get rid of the random ones, might require me to rework some of floors with narrower hallways so the player has room to dodge them but reckon it should be doable in a later version.
The graphics and animations were made by a user called Marumugi4510 (all from this pack: https://koji-marumugi.itch.io/8bit-retro-graphic-materials-all-in-one-pack). Think he's also made an NES collection too but I haven't had a chance to try it out yet.
