Nice, great start for a first project!
I had an issue, maybe it's just with the web build. When I run the game it opens fullscreen and it seems to throw off the aspect ratio of the game, so Zeus spawns outside the bounds of the map. It makes the enemy behavior a bit wonky as well. There is a way to lock in the aspect ratio/window size for your game so this doesn't happen, I would look into that for your next project, or if you intend to expand this one.
The game was fun though and I liked all the sprites! I also love the idea of Zeus drinking a bunch of coffee and zooming around lol
