Created a custom backpack system that integrates with a custom hot bar as well. I used "ToolBarPlus" to aid in creating a "Roblox" - like toolbar up on top for the backpack system.

Using a timer of 5 minutes, new seeds would be restocked to a set number quantity. This mechanism is similar to that of "Grow a Garden" and "Plants Vs. Brainrots"

After the NPC's (in this context, "Zombies") die, you receive a "Crate" that has a set rarity depending on the NPC that died. You can place that crate on of the platforms and "claim" the NPC that died.

Created a custom settings system where you can control Music, SFX, Display FPS, toggle Camera Shake and Notifications on/off.

Created a custom character selection GUI when the user steps on a part. Using viewport frames, I was able to showcase the models/characters in 3D with added rotation for effect.

Created a plot system, assigning each user their own plot, with a maximum of 6 users in the server. Also created a shop system where users can purchase "fruits" with a specific quantity, from which they can feed their "Slime" and make it grow.

Customizable dialogue for any NPC you need. Uses a viewport frame to display the NPC model (also customizable). 

These pets have been scripted to create a basic "semi-circle", with Tween and CFrame modifications + RunService to follow the player's "HumanRootPart" around.

Using CFrame and other OOP (Object Oriented Programming) scripting, I was able to create a similar affect to that of "Doodle Jump"; progress the obby vertically and avoid the spikes while collecting coins.
