After playing for < 10 minutes it started getting noticeably slower and my MBP Retina was spinning up its fans. I am using latest Chrome. Is this a sign that web games are not yet ready - or simply that either the game isn't optimized enough or perhaps even that Chrome is a poor choice for browser games?

My desktop is a E5-1230 v5 (i7 class CPU from 2015) and I played for 15-20 minutes with no noticeable slow down or increase in fans. I was using chrome.

I think your experience has more to do with laptops being much slower than desktops than anything do with how poor chrome is. As for "optimized enough", seems like the whole point was to put non-trivial physics in the game, and not to cheat.

Am I the only one experiencing a game-breaking bug/behavior? The D thrust gets stuck on if you press it once, and randomly the W comes on and gets stuck too. Also, after the first ship, every additional ship starts with W and D thrusts on, permanently.

Doesn't happen to me with linux + chrome. Just finished all 8 levels.

Thanks for the tips. There are always ways to improve the gameplay. I had still 2-3kB left at the end. When I designed the buildings I thought actually about "Save New York" on the C64. https://www.youtube.com/watch?v=ZMUvi6UIV3w

I was reminded of 'space taxi' (which I guess was just a lunar-lander variation, come to think of it). "pad 5 please"

"Up please!" - Yup. What a blast! https://www.newgrounds.com/audio/listen/277378

"Space Taxi" added a bit more depth to the lunar lander concept by adding multiple pads and various vector fields for gravity to act in. Some game modes would accelerate you not downwards but instead towards the center of the map, away from it or around the center in a circle some way. Quite the brain-teaser for my kid brain back then that hadn't previously been exposed to physics/maths like that.

Alright :) so it's back to normal now, right? Thanks for trying!

No I just switched the links. The game on github points to the official entry. The link below points to double speed game.

I see :) made it to 10k points now

This is great! I would love love a boat maneuver game with the same engine. A killer simulator would be one that takes into account wind and current, single vs multi-engine, bow thrusters, prop walk, etc.

Note that this is different from the sailing suggestion below, which has all kinds of three dimensional aspects to. Purely thinking about e.g. docking where all the controls you have is thrust and rudder.

Does not work in Firefox 60.2.0esr. Worked fine in Chromium (10004 Points, died once).

Works for me (tm) in Firefox 61.0.1 (64 Bit, Linux)

Not working in Firefox 60.0.1 (64 Bit, MacOSX). The game runs, but the lunar lander blows up instantly when the game starts. The audio is only in the left channel, but works, as does the space bar toggle for sound on/off, and the explosion uses fluid dynamics which are working.

This game was brilliant fun, just got over 12k after playing it over and over again. It really reminds me of white water rafting, you really can move very efficiently, quickly and with little thrust if you properly read the course. Simple game, but great depth.

Awesome! I encourage you to add it to the science-based games list https://github.com/stared/science-based-games-list

Thanks stared. I forked the repository and will make a pull request. Also I have seen your quantum game project.

Added!

Nice to hear that, BTW.

For this game - any idea to expand it? I finished 8 levels in one go, and it seems that there is a lot of potential for even more challenging currents, whirlpools, floating pieces, etc.

(Side note: mechanic-wise this game reminds me of UGH!: https://classicreload.com/ugh.html)
