Thanks for the feedback! Currently, the active development of this game is underway. We added cooldown and now you can't use an alligator for example 2 times in a row. About experiments, you are absolutely right, combos are about experiments! We will try to add something that will make the player experiment, and not sit on the alligator\bear\alligator combination.
If you expand the game and add a store, (there will be no loot boxes there! Honestly! And donat will not affect the game) then how not to show the player what he buys? Although this pushes the player to do experiments =) You've given me something to think about.
