Project Dogwaffle’s Howler 2020 has been released for free on Windows, although you are “encouraged to make a donation to fund future development”. As noted here on this blog, v.2020 saw… “a revamp of the legacy brush engine, new paper textures, and rationalised de-cluttered media presets”. The latest release is Howler 2022.1, which is several bounding doggie-leaps ahead of 2020. But still only $77 for a perpetual licence. Definitely worth a look, and you’re sure to find a use for it at some point.
