Thanks for playing Barako and for noticing the switches on that 2nd floor. I had copypasted that stair event from another floor that does require 2 switches and forgot lol. The island floor where you push the colored boulders, you were so close to finishing it! When you push a block to the right Star of David, you have to press the action button ONE more time. I don't know why but it's the only way for the game to take notice of the boulder's XY co-ordinates, which is what confirms you pushed it into the right spot. If you activate the yellow and blue boulders, you open up bridges to get behind the red boulder, so you can push it forward properly. If you mess up you're fucked and that's my bad, I should have added a reset button near the start and will be doing that.
I deliberately left out saving because I want players to "accept their fate", no matter what, and that's why there's randomization, to make playthroughs a little more fun. Walking speed in my old games used to be extremely slow and I realize now it sucked but this is a good medium because I find default RPGMaker speed to be too fast, as a fan of old RPGs, especially NES ones like Dragon Warrior and Final Fantasy (before the run button). And the reason you don't have many spells or ways to differentiate the characters is because the game is only 3 floors right now. If you make it down to floor 10 or 12 or something, you'd have accumulated a lot of spellbooks (in fact, some treasure chests guarantee at least one spell, and you have a huge chance of getting Heal by the first boss) as well as stat seeds (like from Dragon Quest). Random equipment also makes for varied character "builds", so with some diligence you could make proper mages, paladins, etc. I don't know how to add item stealing to RPGMaker sadly so no rogues I guess. But by level 10, with different armor/weapons, deliberate stat boosting, and varied spells the characters can become whatever you want. That's why they start as blank slates.
Also, the wizard guy you talked to raised your party's stats by 5, permanently. He has a 1 in 8 chance of appearing on a floor, just a fun little boost that I remembered from playing Dragon Warrior Monsters. I'll add dialogue to confirm that's what he does so there's no confusion, thanks for helping :)
