Hi! I recently re-released a few older freeware games of mine and put them on Steam.
https://store.steampowered.com/app/2...de_Adventures/
The games included in this collection are:
A Game with a Kitty
A Game with a Kitty 2: Darkside Adventures
Treasure Hunter Man
The games all have exploration aspects, but Treasure Hunter Man is probably the most 'metroidvania'-like. There's grandpa-style pixel graphics, original music (thx @ Sean Cameron for making the AGWaK1+2 music) and they're probably kind of retro hard.
These are re-release versions and can be played in fullscreen on modern systems or a resizable window. The keyboard shortcuts and controls are on the steam page.
If gamepads don't work for you, enable legacy input support for input devices in Windows.
Thanks for playing & Happy Merry Holly Jollies!!
