I'm working on a game called One Cannon, One Army (abbreviated to OCOA). This game is about using your cannon to shoot various projectiles at different types of aliens to stop them from destroying the earth. You have a guide (who is basically the tutorial) named Tucker to aid you in your mission. Additionally, you can purchase more powerful weapons and upgrade your cannon as you level up, but the aliens will become more difficult as well. Eventually, you'll face the boss alien (I still have to come up with a name for him/her/it), which I have already coded (the boss is immune to all status effects and shoots lasers at you).
The game also has achievements, which add more goals to the game other than defeating the boss.
Here is a gif of the gameplay so far...
Sorry that the video is so choppy (the actual game isn't like that). If anyone can recommend a better free screen recorder, I'd be glad to use one that records better videos.
