One word:
Enemies!
They come in three colors, and each one has different properties:
the Reds have average speed and health,
the Purples move slowly, but are durable,
and the Blues are weak, but really fast.
Every two seconds, a random enemy will spawn at one of 6 points just outside the right edge of the screen, and head left from there. Once they reach a certain point, they shoot the purple orb that I showed in the last post, which heads towards the position the player was at when it was fired.
The player dies in one hit from touching either a bullet, an enemy, or a pipe.
You get different amounts of points depending on which enemy you kill, with Blues (and pipes) giving you the most points, while Reds will give you the least.
Now that I've made the enemies, the game is basically done. I'm not gonna submit it now, though. There are 9 days left in the jam, so I'm gonna try and implement some more features, like...
- A counter that displays how many pipes you've passed,
- Tips on the "Click to start!" screen,
- Saving your high score after you've exited the game, and an option to reset it,
- Multiple backgrounds,
- Difficulty increasing the longer you stay alive,
- Bosses, etc.
I most likely won't be able to implement all of those, but I'll try and do some of them. In the meantime, if you want to play the current build of the game, you can do so here. Press left-click to flap and hold right-click to shoot. I'm looking forward to hearing your feedback!
