Wow, that works really well! Nice overall performance!
What I would like from the game is
- The land which is uniformly tiled might need to be shaded by, like a "macro detail texture". I think I just invented that term. :-/
Think of your tiles as the detail texture, and i think the map needs a coarser texture on the top of it. You could probably just blend
larger images across, or maybe just pick from a more varied tileset - Even if the map is all grass - A little plant here, a fern, small stones etc. Debris.
- A way to know that an order has successfully been issued, and as such is "acknowledged!" (nudge, nudge! ;) ) - or maybe displaying a cross below the mouse cursor,
to indicate that the unit knows where the player asked it to go.
- Sprites that change instantly, and don't flicker when they turn.
- Explosion sprites that don't exceed their image boundaries and look like yellow rectangles with rounded corners.
I know you guys are limited by the canvas performance, but some simple particle effects would do the game good.... Also, you could use a particle system
to have the vehicles leave tire tracks in the snow, or as mud in the grass.
+ Another improvement could be decals. You could use a particle system to manage these too, but just think scorching the earth with a black region where a missile just landed...
- And, oh, -the sound effects are
really annoying!
