As Lasermagnet Games (my friend Tibor and me) we've joined the Toy Box Jam 3 in early Feb 2022 and this time we didn't fail time management miserably and were able to maintain focus quite well, especially compared to most of our game jam attempts.
Although I'd still call Copterfields just a prototype due to the lack of content and suboptimal balance, I was (and frankly still am) quite satisfied with the end result. The game received a couple post-jam updates (including local multiplayer support), but development was halted in March 2022.
The last build is playable on Itch and I've kept a devlog during development too.
I have no plans to continue development.
