Great job on learning the engine, and finishing your game, it's pretty good for your first time with the engine. Art is good and sfx are pretty decent, although I would've liked a simple background music.

I found out if you go off screen you can't get hit, which makes the game pretty easy if I do say so myself. During one run, after grabbing the 2nd upgrade, enemies stopped spawning, so that was a bummer.

Even though it's rough around the edges, it's still a fun and decent game, I liked and enjoyed it quite a bit, thank you for creating!
