Billiards
Created a complete two-player billiards prototype with custom physics.

Mini Golf
Created a mini golf prototype, building the full project and extending the custom physics from my earlier Billiards prototype.
- Adapted my earlier physics work for mini golf, with collision checks focused on nearby walls.
Money Temple Tycoon
Created the full game, combining tycoon progression with a clicker levelling system and timed collection challenges.
- Built a clicker that levels up after a set number of hits, increasing both its money rewards and the hits needed for the next level.

- Implemented rebirths earned by purchasing everything in the tycoon, which players can then spend on special items.
- Added timed rewards, cosmetic hats and personal high scores.
