LabChurros' games like Project Delta (full 3D can jump and grow and shrink to normal size, no combat or interaction besides able to crash buildings) and Project Oasis (you with shrink ray go around and shrink giantesses), Growth RPG (full 3D but can't jump and combat is turn based but you can grow to absolute ridiculous sizes especially with editing to maxx your resources), The Essence of Gender (full 3D can jump, combat is turn based tho) on TfGames Site , Bloom War and A Growing Adventure, Ezkos' Diminishement or shomething like that, Fantasy Opposite , Crystal Wish (3D , can jump and some fun gameplay around giantessess) and all other games of that dev (less jumpy sometimes not 3D in nature), Soulstream Expansive games (2D, you can grow ladies) , Sakura School Simulator (full 3D and open world but it is Mobiles-only ,girl character has Alice in Wonderland costume that can grow or shrink (3 sizes) AND she can grow or shrink people that she grabbed , you can shrink or grow people even further than max growth, if people are giants and collision is On they will knock you and take your health or knock out other people around, it is mini-GTA, also can grow or shrink via glitching by sitting on spawned furniture and shrink or grow furniture along with that character (you or someone else) you can make giant character into very small but dealing giant character's damage (kinda like Atom/Ant-Man/DollMan logic), also you can romance anyone in this game by romance = only kissing or hugging ), there is also weakening spell in Dark Missiah Might and Magic that permanently shrinks enemy (or friend, sometimes locking you on the map) but you can only use it consisently with cheats and I am not big fan of perma shrink stuff when it is only cruelty also not big fan of high pitched voices idea (you can literally turn entire map of enemies into constant scream of high pitched knee-height people running around scared) and when you approach them your character autmatically stomps them even if they are friend.
I wish someone knows more, especially 3D games like Sakura School Simulator, if only it wasn't Mobile only (and therefore also more NSFW optionally), but on the other hand it is great because you can play SSS everywhere and it isn't very heavy in terms of digital weight.
