Interesting concept which I could see being very popular, and cool to see the inspiration from the Amiga game.
Currently it's a little hard to assess, as I feel there isn't really any player expression in the game--at least in my playtest. The cards were dealt randomly and I could only turn them over randomly, so the actions I took during my turn always felt totally random, and I couldn't craft a strategy about what to do. Dealing the cards face up could help this allowing the player to string together actions meaningfully, while retaining the deck builder RNG.
It also felt a bit unfair as the opponent appeared to always have many more cards than me, so I felt hopelessly doomed to fail.
Menus, graphics and information are also quite hard to read currently as there isn't much hierarchy, but I understand this is very early.
Like another commenter I also had the feeling assets were AI, which was kickstarted by the thumbnail which is very uncanny and feels generated. This generally doesn't feel great especially when they are the only assets in the game. So unifying a visual style (even if it's all placeholder) would make a big difference user wise.
Ultimately, it's a cool concept that could be fun. But currently the very heavy RNG and lack of player information is a bit of an obstacle.
Please try my game if you get the chance :)
