I think i can write browser based editor with map(original formated) downloading. It's easy in compare to real game with live mobs. I even can do static game walker with full in-game editing online. (Just based on existing information + nee read wall flags)
May be in next weekend because too busy onto work-week.
At this weekend nights, i already make map viewer who can open maps online from published game folder. (Unpacked resources archive).
One version shows 2d top-down view, other real flight over map in 3d, but with one sized sprites (i'm don't set size manually). HTML+WebGL (Vue.js, ReGL)
IRL i want more difficult task. But every time when i write new game, i just demotivated before it's view cool.
With LAB, it's already loved game (finished 8+ times), with existing maps.
I want to recreate original game, with online platform. (Can share source, if you want online HTML5 version with originally tuned parameters)
Then i want convert box based levels into something like doom (keep gameplay), but portals instead of BSP and expand it. As final i want rooms with independent space-metric to achieve unlimited-sized levels without "loading" and ship flight mechanics. But it all needs more time, and motivation. Every time when i try write something, it's runes by ugly view and no game play earlier than i write it with too complex engine. Countless times i parse other games and make map viewer, or scrap info (like morrowind alchemy search with deep respawn analytics). But i just can't write something own too simple to be playable in first 3 motivated days.
Sorry for alot of text, i just slightly obsession about gamedev from childhood, and now in my twenty eight years, i stay have no games other than tetris like because more knowledge make me more wishes.
