I like the game, but there are many problems. It would be much better if there was at least a little randomization in the landscape. Pretty much the only thing that's random is the items you get from shops and chests.
Also, it seems like there's no way to tell if an enemy that's too strong for a normal attack will be vulnerable to your special attack. When I was using the dark mage's ice spell, sometimes it would kill the bad guys with the exclamation point and sometimes it wouldn't.
There's a glitch where after you leave a shop sometimes your controls will be frozen and you'll just slide along the ground until something happens to you like you get hit or fall.
The thief's invulnerability is misleading. It only protects you from enemies, not spikes or pitfalls. I guess it makes sense since it should be called invisibility.
I think it would be nice if the priest's free feather regenerated every time you touched a priest statue, instead of just getting one save for the entire run. Maybe each job could have a one-time use ability that regenerates when you touch the statue.
