Can we have multiple "Mardi Gras" songs? The same one over and over gets a bit repetitive. Perhaps a Jukebox..? Or perhaps upon getting X amount of upgrades? Would just be nice to have something different... Love it overall. =)
Really reminds me of Digimon in terms of the Monster designs, and really reminds me of Monster Rancher in terms of the gameplay. Like, in every aspect of the gameplay. I mean, maybe it's coincidence but it looks to me like you just made a flash version of Monster Rancher =P
Can't wait for badges. This game is a massive improvement, but loses nothing that made the first one so great. This is a perfect example of how games should improve!
Perhaps rather cowardly, I found it best to let the Unholy temple to become a battle of attrition. I cast Venom Touch, stuck on Regeneration and just kept going for 4-comboes for healing and hitting when Rage filled. I ran Magic Arrows and Create Energy as a weak attack but ended up not using it too much when Energy ran low (so Regeneration didn't untoggle). I also had Wealth and Create Ice just to help clear the board a bit although there are probably more efficient ways to do so but I find this nice for getting the Treasure too.
With pegs, just group stuff together "logically". You'll know when it's right, because you wont be able to move them anymore. Just try a few possibilities, and slowly you'll slim it down.

For all spells it is there. In next updates or builds I am planning to put special effects for the spells.
