To Jimena and her little brothers Anita and Fidel.

Jimena liked to play Ceed Universe, but some times it stop working... so... for months I was trying to install it on my computer using Debian 10, and I couldn't make it work emulated or with a chroot. Searching in Internet, I found 4 similar games: Colobot, Minetest, Code Combat, Liberation Circuit.

Colobot

It work out of box!

apt-get install colobot

Minetest 

I install it from debian backports, because the package in the normal repository use python 2.

echo "deb http://deb.debian.org/debian buster-backports main" >> /etc/apt/sources.list
apt-get update
apt-get -t buster-backports install minetest

 Code Combat

Need to be updated... but with these commands works...

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash
nvm ls-remote
nvm install 8.15.1
node -v

curl -sL https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list
apt-get update && apt-get install yarn

git clone https://github.com/codecombat/codecombat.git
cd codecombat
git remote add -f upstream https://github.com/codecombat/codecombat.git
echo '{ "allow_root": true }' > /root/.bowerrc
yarn install --ignore-engines
yarn run webpack -- --watch
yarn run proxy

Liberation Circuit 

It seems to be a awesome game!!!

apt-get install liballegro5-dev liballegro-image5-dev liballegro-dialog5-dev \
                liballegro-audio5-dev liballegro-acodec5-dev
git clone https://github.com/linleyh/liberation-circuit.git
cd liberation-circuit
make
bin/launcher.sh

Don't forget the excelent programs to learn: scratch and python3-tk.

Thanks!
