This is a fun and addictive game, I love the retro arcade vibe to it, and the sound design really adds to that feeling. Overall this is very impressive for a game jam game!
Changing the window size was an improvement from last time, and adding particle effects after killing an enemy was also a good call. It feels more polished now. I also love the addition of the leaderboard, seems like a perfect fit for a game like this. Congrats on winning the jam, it was well deserved!!
