A Rogue-lite Isometric bullet hell where the player must absorb bullets to attack.
That prototype is an attempt to remake one of my previous game jam entry into a full game. It got a pretty solid bullet system, stats, item effects, custom collision and other neat features. All of these were also adapted to a 2d isometric projection.
But, while I'm proud of what I achieved on that project, the 2d isometric presentation added just too many unexpected technical hurdles to overcome. I might revisit that project in the future but using a 3d presentation instead.
