Good game, though I found a couple of bugs/glitches:
-If you save when a character has extra XP or DP (from a bubble) this is lost when reloading.
-Equiping bubbles as armour does not give the claimed immunity to traits (e.g. character's with a lvl 3 poison bubble in their armour still get poisoned just as much as without).
Other than that the few other problems (too many battles per travel etc. are already widely reported here).
