Very fun and cool, would've liked an expansion upon discovering islands and more technology to explore. Also, the dark dimension is a wonderful idea! Although it seems a bit bland and useless (the gem only has one use). Also, there is a clipping problem for the objects, they just fall through the terrain. Anyways, I rate it 8.5/10. Lovely game, could be expanded upon more.
Thanks for playing my game! I'm glad you enjoyed it. I've stopped development on the game, but if you're looking for more technology to mess around with, my friend made a mod for it which adds a bunch of new items and features: https://microman502.itch.io/redrift
