BooBoo
BooBoo is a unique, mini game engine/programming language, designed to make creating games from scratch fun and easy. The launcher, with its powerful API, and SDL2 DLL add just 3 MB zipped on top of your game. You can begin drawing shapes to the screen as simple as defining a void function plus a primitive drawing call. It's a bare-minimum engine and powerful API, allowing you full flexibility.
The download also includes a CLI version of BooBoo that supports text colour changes and unbuffered input, for making console games, apps and tests.

BooBoo comes with a plethora of examples. Here are a few of the games...

Example
Here is Pong in BooBoo:
; Get the default screen size - that's what we'll use
number SCR_W SCR_H
get_buffer_size SCR_W SCR_H
; All of these numbers define the game, from sizes of ball and paddles, to positions and speeds
number PAD_H PAD_W BALL_SIZE BOTTOM score1 score2
number pad1y pad2y ballx bally balldx balldy
number BALL_SPEED PAD_SPEED GUTTER
; Set these values to defaults
= BOTTOM 50 ; 50 pixels at the bottom of the screen for score
= PAD_H (/ (- SCR_H BOTTOM) 8) ; paddle height (1/8th of the screen)
= PAD_W (/ PAD_H 3) ; paddle width
= BALL_SIZE (/ PAD_H 2.5) ; ball size
= score1 0 ; default scores
= score2 0
= pad1y (- (/ (- SCR_H BOTTOM) 2) (/ PAD_H 2)) ; position paddles in the middle
= pad2y pad1y
= BALL_SPEED 2.0 ; default speeds
= PAD_SPEED 3.5
= GUTTER 15 ; space between edge and paddle
; Set the ball moving left/right randomly

AshEdit
AshEdit can be used to take advantage of BooBoo's tilemap features. Various styles of 2D tile-based games are supported. Regions can be marked with user-defined integers or bitfields, to mark those "question blocks" in your platformer or chests in your JRPG.
AshEdit has a full suite of tools for creating and editing layered maps, from rich selections to macro recording.
Media
Linux
BooBoo and AshEdit work in Wine. AshEdit needs the Arial font:
$ winetricks corefonts
