training a neural network to play a bullet hell game

cross-posted from: https://programming.dev/post/14979173

• neural network is trained with deep Q-learning in its own training environment
• controls the game with twinject

demonstration video of the neural network playing Touhou (Imperishable Night):

it actually makes progress up to the stage boss which is fairly impressive. it performs okay in its training environment but performs poorly in an existing bullet hell game and makes a lot of mistakes.

let me know your thoughts and any questions you have!
