I didn’t expect to see a pinball-style game in a game jam – that’s awesome! I really like the execution and the point-collecting mechanic.
The next step in development could be adding more resources, more elements on the board, and some form of competition or challenge.
You should consider adding a web version (not everyone wants to download an .exe file). I made the same mistake at first, but eventually added a web build – and it really paid off.
