The first one is L'Épopée Spatiale by French player assiette. Some levels are very technical and require finding efficient ways to solve, others will test your ability to traverse slippery ground.
The second one is L'Antre du Ninja by French player and Eternalfest member moulins. The whole land uses the Ninjutsu game mode, although the "hearted" and "skulled" fruits are always the same. Even though some levels can be very frustrating, most are designed very well in my opinion.
