When I started my first GMDanmaku project I did it as a way to teach myself basic programming. It ended up being an excellent project for that and it got me thinking of what’s next. After dabbling in some other projects I decided to make a game/tool people could use to learn programming in a similar way. Being somewhat inspired by the Touhou community lead me to decide on making a Touhou Shmup making engine.
I did a small release of this engine on my YouTube channel a few months ago and haven’t updated it since but rather than leaving it as another unfinished project I thought I would fix the reported bugs and re-release it here, along with the source code.
