My tips for your first jam~
- 2D top down shooters or endless runners are the easiest (just find a tutorial/YT vid)
- Make sure you make your game a WebGL browser game (get more plays/feedback)
- Ignore mean comments and leave good comments. A good jam comment should be, a complement, constructive feedback, end with complement. (As to not demotivate devs hehe)
- Great games can still just be simple shapes (don't worry if you can't "draw")
- Finish the game the best you can and be proud~
