Nice! The new track does make it a more enjoyable experience. The visible weapon sprites look pretty good too.
If you plan to develop the game even further, I would love to see more variety in the level tiles. Stuff like tile variations and general decorations, to make it more visually interesting. It would also be cool if you could add stuff like spikes, moving platforms or other things to make the platforming part of the game more dynamic.
Anyway, cool update overall! I'll be looking forward to the next ones.
