How far can I go with html5 and C2, performance-wise

this is my 640, 360 layout size

and this is relatively the size of a level i want to have, i'll have a bout 4-5 levels like this thats all

filled with sewers below and apartments above ground, so fairly full visually - apartments have individual platforms, sewer too, 2-3 parallax layers on background, about like 40 npcs

the game's gonna be for desktop, can i make this in C2 without final product being low fps and such? i wonder

would also love tips, tricks and tweaks to not have such a thing, im very noobish so

The number of levels doesn't matter with regards to performance, just the content of each level.

I'm getting 60fps in the desktop game I'm working on, and that has:

• 16384 x 4096 levels, with Characters around 48 x 64 to give you an idea of the level size
• 6 layers: 3 background/parallax, playable layer, HUD layer and Menu layer
• 30-80 NPCs with Platform Behaviour (for movement)
• 40-80 other objects (e.g. boxes, barrels) with Platform Behaviour (for gravity, when terrain destroyed below)
• 3000-4000 destructable sprites (a Tilemap might have been better if performance was bad)

A few tips that helped me get good performance:

• Use Triggered events (ones with green arrow) instead of regular events where possible
• Similarly, use Timer behaviour or Functions to call certain actions at certain times rather than constantly checking for the right conditions
• Use Groups, so you can disable/enable a whole bunch of events as needed
• Use Spritefonts instead of Text if you need to update something frequently, as updating Text every tick will impact performance
• Destroy objects outside the layout (i.e. in the margins), a platform object falling into eternity will drop your performance
• Disable collisions when not needed e.g. only the surface of my destructable terrain has collision turned on to start, I turn it on for each terrain piece when it's exposed or made accessible
• Disable platform behaviour when not needed e.g. I only turn platform behaviour on for my enemy units when they are on screen

a platform object falling into eternity

lmao

thanks for the thorough answer, very valuable to me
