Maybe i like your game, just because i'm bored with rpg, and too much visualized games.
But your game like fresh breath, with simple graphics and easy controls.
The latest time i most played in 2D games, like Crimsonland and other 10tons, and management games like factorio. Too tired with quake, and too uncomfortable with doom (i tried most emulators, but hmm, just feeling wrong).
Your game for me, like symbol about, simple graphics and 2.5D also can be enjoyably.
I try write games lot of times, and every time i buried up under premature optimization and too big list of wants, to make it while free time... But you make it's so good without all of this shit, what i want in my games. And it's just magnificent.
I tryed to remake your game, with hope about extend and make my own. But unfortunately, i can't just write simple game. I can't just keep simple 8byte per field map like you, and make maps manually. I need to make large maps with ray-tracing to render optimization, with real entity system and multiplayer sync, with variable field height and AI lieutenant that controls other, with map generation and portal vision... And i can't make in over night or two before burred under work tasks... And when i understand it, i just play LAB again to find more secrets... (= It's story of two last weeks. Under that time, i wrote simple game (js webgl reGL, no engine) two times, and both time stacked with no ideas how to solve problems because i can't restrict myself with features, and can't freeze api.
Sorry for my English and nagging.
