One of my biggest complaints (that I don't already see mentioned) is the map. There's no order to the strength of the battles on the map, and no way to preview the strength without hovering over each one. It'd be nice to see the strength of each battle when you view the map and/or have the nodes in some kind of order.
What's the secret to getting the bug to appear? There was a comment that said you had to click in a specific spot, but no mention of what the spot was.
Another game that wants you to babysit your village but wait around for energy to actually do anything with your heroes. Engaging for long enough to get the easy badge, too grindy for most people to continue past that.
Is there a way to apply multiple upgrades at once? I just unlocked a new column and want to catch them up to my other creatures, but to do that I'd have to click each one 30+ times instead of clicking blocks xD
It's frustrating to try to level lower-level critters. I caught a plant critter, and figured that I would find water-type critters by the water to level it against. No such luck; I found a bunch of fire-types that one shot my little plant. After four goes of this I was out of the ability to heal them for either a few hours or a few dollars. That was enough for me.
