Aquaphobia - 2D XNA Platformer
This summer, I have been part of a game project that has submitted a game for the Microsoft Dream Build Play competition. The team consisted of 7 individuals: 3 programmers, 1 designer, 1 artist, 1 producer, and 1 project manager. The project spanded from end of May to the beginning of August. The game features 2D platforming mechanics, per-pixel collision, HLSL, physics, OOP, and sound. I was in charge of player mechanics and movement, per-pixel collision, and the game sound. Below is are samples of the gameplay mechanics and player animation.
