I managed to finish one of the enemy AIs, nail down the side-scrolling, tossed in the placeholder and scripts for the death animation, made a short song for the credits and direction parts, and I put in a functional pause button. The downside is that pausing will requires a middle mouse click for use, as pressing any keyboard key will cause the game to unpause. Right now, the majority of the prototype phase is completed. The next few weeks will be based around planning and plotting the stages, creating more enemy AIs, working on various music pieces, hacking out the various lose screens and stage transitions, and working out the bosses. Stop by next week for more updates.
