Loved this! Back in the mid 90s, Sierra developed a game called Marble Drop that I played a LOT. This game, in an odd way, captures a very similar aesthetic. The colorway, graphics and puzzle-solving loop just bring back a familiar feeling which I really appreciated.
And a really neat puzzle game idea at that! I would have liked to get a bit more info about what was going to happen when each individual part was used - whether that be through a graphical preview or tooltips or something, I am not sure.
Not much else to say about it, other than that. Beautiful graphics, interesting idea, lovely game. Thank you for sharing!
