Engines

Defold

LANGUAGE: Lua
PRICE/LICENSE: FOSS

Lua powered fully featured game engine that uses messages instead of signals/methods.
Developed by King Studio (Candy Crush) as in-house engine and got open-sourced.

Bitty Engine

LANGUAGE: Lua
PRICE/LICENSE: FOSS (Precompiled is paid)

ImGUI powered game engine that feels like PICO-8 on steroids.

BASIC8

LANGUAGE: Custom BASIC
PRICE/LICENSE: Paid (15€)

Basicaly the same thing as Bitty Engine but you use BASIC instead of Lua.

Enigma GameMaker

LANGUAGE: Visual
PRICE/LICENSE: FOSS

Open-source re-implementation of Legacy GameMaker. Uses the same visual programming language as GameMaker.
If you used GameMaker before I highly recommend tring this out.

UXN

LANGUAGE: ASEMBLY (CUSTOM)
PRICE/LICENSE: FOSS

More like a Virtual Machine than a game engine. Uses custom ASEMBLY Language and compiles to binary roms.
I tried it for little bit and it's very hard.
