Little post jam update for our Sega Master System game

Our submission turned out great, but we had a few art assets that were made during the game jam that didn't make it to the final build. Our sleep deprived brains also missed some obvious performance optimizations. So we made this little update for the game as it deserved to be polished up a bit.
Gameplay and level design have remains unchanged.
Changelog:
- Player two sprite is no longer corrupted
- Map tiles that didn't convert correctly now convert correctly
- Pollen and enemy bullets are animated
- Main menu art implemented
- Story text animated
- Performance, especially in two player mode, has improved notably
Thanks for everyone who has played our game already!
