A hoard of monsters has tried to invade your tower... Unluckily for them, you're a talented mage! Spells: [Z]-Fire [X]-Meteor [C]-Gravity Monsters can be crushed with moving crates, they are not despawning.
Honestly, this is one of my simpler projects, but if you look inside, I've been making one sprite for every spawnable object. That's about as complicated as the project goes, but also the background movement. Comment what spell I should add next!
