Huge congrats on finishing your first game!
It's very janky, and definitely rough around the edges, but you got a lot of core things down for a boss rush:
- different attack patterns
- boss phases
- demeanor, the bosses are huge and you can really tell that they're bosses
For me though, the game just wasn't that much fun. Picking up toothpics and throwing them doesn't have depth enough to be interesting for me, and I didn't get further than the first boss. To me, it just wasn't interesting enough. Some highly recommended reading:

The only way to get better at this stuff is a combination of research, reflection and just doing it a bunch of times. So keep at it! You are off to a really good start, you just gotta keep going!
