What is the crowd's opinion of SuperTux?

From 3.5 billion comments

There are games that have already done something similar:

Secret Maryo http://www.secretmaryo.org/

Super Tux https://www.supertux.org/

Both games are open source, so you can find author e-mails and ask them if they had any problems. The games have been out there for years, so someone would probably reach out to them by now.

I like the following games:

• SuperTux: A game similar to Super Mario Bros.
• Neverball: Clone of Super Monkey Ball using SDL/OpenGL
• Hedgewars: A turn-based strategy, artillery, action and comedy game
