After two days of hard work, I'm finally able to release what I've done these two days. Here're what I updated:

• Great improvment on the "lazy rendering" system - now supports objects that have an unified animation (e.g. Dots, which have a flashing animation; even more complex animations like Lion Blaster can work now). Majority of objects now use this rendering system
• Thanks to the improved system, the game's performance is much better
• New system for maps - now maps can support two layers of blocks/objects, mainly used for placing collectables (e.g. Stars, Regen, etc.) on top of non-solid objects.
• Due to this new system, all maps have been changed slightly
• Speaking of maps, the Lion Blaster level now uses less bounce pads
• Updated star animation
• Updated explosion

• Small updates on the background
• Small changes to the camera - now moves less when the player's moving

• Removed the FPS display, and the function of pressing Esc to show hitboxes
• Small bug fixes
