I always wanted to do a Banana Nababa type of game.

So what i will do for this miniLD if i have the time is a boss arena type of game.
Maybe 5 or so bosses with escalating difficulty.
Vertical attacking pattern.
Shoot in arches by default and hold up to shoot straight up.
Basic platforming with doublejump because its awesome.
And ofcourse challenging boss designs with an impossible endboss.

Artwise i will keep to some restrictions
2 colors per player, critter and tile (4 with black and transparency).
3 colors per boss (5 with black and transparency).
8×8 tiles and sprites, excluding the boss.

The game is set in space and you are at The Last Boss!

Updated with some early progress
The One Hour Game Jams have so much basecode collected i can just pick what i need!

Banana Nababa
It is an awesome and difficult game, definitly worth a download.
