[TOMT][FLASHGAME][MORE OR LESS 2010]A game about Monster fighting in a tower, pokemon combat stile

I can't remember the name, and I've been looking for it for years. The game is about monster battles, like Pokémon. You start at the entrance of a tower and can choose between two creatures that look a lot like a lion and a boar. I don't remember if there were more. You have to fight other types of monsters in different rooms as you climb the tower. There were different types of biomes. At the end of a level, you enter a room with a cache of eggs, where you can choose one that will hatch into a new creature for your team, this is the only way that I remember where you can get new creatures. The combat system is 3v3 turn-based. I don't remember if there were bosses, but I assume there were.
