Creating the shop and inventory UI was a significant challenge, especially without the final art. I had to use my imagination to incorporate all the elements. We aimed for a shop to buy new spells, display spell attributes upon selection, and a UI tab to view and equip owned spells by dragging them into slots. Although I had previous UI experience, this system was on a different level.

I decided to learn scriptable objects so I created a scriptable object script to store all spell data. This data stored things like the title and description to damage and range. This allowed easy access to spell information anywhere by referencing the scriptable object. When a spell is purchased, it’s added to an array of owned spells. Dragging a spell into a slot equips it to the player's staff. This approach lets us add new spells without changing any code.

I was also tasked with creating the game's enemies. The players fight an army of bears, and I wanted each enemy to be distinct. I started with a base enemy script to handle common functions like taking damage, dying, and setting its spawner. This script included variables for health, movement speed, damage, and the experience dropped upon death.

The first enemy I created was a fast bear that runs towards the player, stabs with a spear, and then jumps back. Using navmesh, the bear follows the player, attacks when close, and jumps back after the attack.

The second enemy throws honey at the player, creating a pool that slows and damages over time. Unlike the first bear, this one maintains distance to throw honey, adding a dynamic element to the level by shrinking the player's walkable area.

The third enemy is a big black bear that acts as the tank. It’s slow but deals massive damage and has a lot of health.

Since our game has no ending and players can continue as long as they complete levels, we needed an effective enemy spawning system. As a roguelike, the game requires a way to randomize enemies each round to keep it fresh and replayable. I developed a system that randomly selects and spawns enemies at various points around the map.

For each new level, I simply create spawn points around the map and add them to the enemy spawner. The enemy spawner uses a weight system: each enemy has a weight value, and spawning an enemy subtracts its weight from the total level weight until it reaches zero. The total weight increases with each round, making the game progressively more challenging.
