I’m so close to finishing the game! First of all, I finished the attack system.
Basically, you answer a certain number of questions under the “attack” button, filling up the bar next to it. When it fills up, you unlock a new weapon. After it cools down, you can use it; but on the first time of cycling through every weapon, only once! As you complete more cycles, though, that increases to twice, then three times, etc.
I also added pixel art to the buttons. I took away the “attack” label of the attack button because the students I tutor don’t know that word yet. Instead, I used an animation in hopes of incentivising them to click it.
The other buttons include:

• The arrow
• Two arrows
• Copper sword
• Diamond sword

Which brings me to my next development––when you click those buttons, there’s an actual attack! An arrow animation, a two-arrow animation, a copper sword animation, etc were added to the mix.
I hope to add music, SFX, and maybe simple instructions for the future.

Finally, I implemented a losing and winning screen using the same node in the system, detecting player and enemy health.
