This is an interesting concept for a game.
I know it might be because of the limited time in a game jam, but I would have liked to be able to merge different types of poison together to create unique combinations that you couldn't buy in the shop. You wouldn't need to cover every permutation, but it would be fun to maybe mix the tornado with a "liquid" poison to make something like acid rain.
I also feel like there needs to be a purpose for making the poisons beyond a bank account because after unlocking all the poisons you can just spam the nuke button and get infinite money, making the idea of mixing poisons or buying them from the shop a bit pointless.
I liked the animals bouncing around the world though, it's fun watching them move around the map.
Thanks for the game
