Thanks for playing. Yeah the art is from my game Crazy Invader ShootEm Down and scaled up 2x so they don't quite look right. The main goal was to reuse the assets I had to create an ultra mini game in a short amount of time that I can use to prototype future tech in my game engine/library.
Just to clarify I do use a graphics engine (Asphyre PXL for Delphi) so I don't have to code up that side of things and it came with basic Rect collision detection and a game loop but yeah heaps of coding beyond that. Just spent 8 hours coding up a proper menu system so that'll end up in this game initially before I back integrate into my other games.
