It's been 4 days since my last comment, I have since then beaten the "main" campaign with half my deck consisting of just frogs which demolish the enemy due to the event going on.
Game is kinda fun, events or whatever you call them kind of break the game since (in my case) I just place a single lava frog or another frog and suddenly the entire enemy lineup is either gone or poisoned. Also like everyone else is saying, REALLY pay-to-win.
This might just be a skill issue on my part but, the game spikes in enemy HP once you get to a certain level and is almost a guranteed loss. Again, this might just be because I suck at the game lol.
Could just be me but my chests are glitched and I cannot open this starter wood chest that doesn't have a timer on it. It won't even let me open it using gems.
