all 2dcg:
Dungeon of Luluu Farea - a "puzzle" rpgm game, difficult even in normal mode, but very aware of how silly it is. has actually some good comedy here or there.
(Play the old WolfRPG version, it has ~20% more content. The official translation cut it not because objectionable, but because -20% means 20% less pay for translation. also official is uglier and WolfRPG let me configure gamepad buttons where official has one important one not map-able to gamepad)
Eiyuu Senki - World Conquest does have a darkish main story, but >90% of the game is battles and character missions, which are mostly silly fun stuff. (long game)
(Play the fan translation for more translated good stuff. GOLD is not an alternative but a game that clearly addresses players who have already played World Conquest and want more of the more-or-less-same)
My memory of it is already a bit blurred, but maybe Nursery Slime ?
