The jump series was my first attempt at making games. I was completely self taught and didn't have any external documentation to figure it out. These games are horrible and my bar for how fun they needed to be was "more fun than the class I am supposed to be paying attention to." While I regret not paying more attention in classes, I am glad I used the time to learn to do something useful like programming.


Jump!
This is the first game in the series. The objective is literally just to get to the end of the map without getting crushed by the enemy dot that is chasing you. Levels are procedurally generated by drawing lines to different heights and you couldn't jump while holding the arrow keys. Due to my lack of knowledge on how label and goto work there is a memory leak. I did not learn what I was doing wrong until well after I stopped making programs in TI Basic.

Jump 2!
The long awaited sequel to the popular Jump game! (No one was waiting for this garbage). In this game I added a gravity switching mechanic where whenever you came in contact with either the ground or the ceiling the gravity would flip. This added an interesting mechanic of trying to find the optimal time to flip gravity so you could always go downhill. You still can't jump while moving I never figured out how in the entire time I was programming in TI Basic.

Jump 3!
Who says the last game in a trilogy has to be the best? In this last installment of the Jump series I put some distance between the floor and ceiling lines. In this game you have to ride the enemy dot up and down to flip gravity. As far as this terrible series is concerned this is easily the most fun of the trilogy. You still can't run and jump which actually kills me in the demonstration video but if I ever was to play any of these this would be my choice.
