Actually yep. I also thought about how to improve them. AI actually would be improved even now (@krakers made some interesting scripts). It would be also nice if they would die after, well, for example 2 hits instead just one Shooter's particle. Aliens are almost always hard to kill, but in original CoLoBoT unfortunately they are just a bunch of nasty p*ssies. Only their sounds are actually strange and scary.
Level structure was changed. So old userlevels will no longer work. You need to manually correct it. I suggest you use this level as an example/template: https://github.com/MrSimbax/colobot-alludo
I´m not sure if that kind of thread already exist, but many userlevels crash with the error bad_alloc. Noidea why, because they are just like other userlevels.
Idea for the fifteens anniversery movie: First of all a practicebot writes CoLobot on the ground and drives away. After that a builder builds a bot factory,into which a wheeled grabber brings a titanium cube,which builds a drawer, which wites Gold Edition beneath and drives away.
Argh, unfotunately I can't force mobile version of Slack to work on my phone until I buy new device. Such a shame, having the last working Xperia smartphone with comfortable QWERTY keyboard in the world and not being able to use it because of badly optimized software... Android 4.0 in not THAT old, am I right?
