I am starting to think that my game could become enjoyable...One day to go. Another coding during the night session... Warm rain outside really helps to feel the melancholic vibe...
I need to add music, sound fx, menus, scores etc. In short: it needs polishing, but it looks that I will manage to make something of it. It feels that it may become half-decent small game.
I have added free subparticles (Electrons (-) and Protons (+)) - it somehow makes gameplay more chaotic (mad?) and more fun (at least for me).
