This reminded me of the Commandos saga! Curious that you used GDevelop, I didn't know about it. Beyond that, puzzles are clear and challenge is easy to understand. I encourage you to go for Godot Engine next, I think the talent you put here would be enhance with a little more parametric control. Great job!

Godot is node-based, which means everything is a part of a giant tree. You build branches and then you put all the tree together. It's free software and you've got a great community and a lot of documentation. You can get it here. It compiles for windows, gnu/linux, html5 and mac. I'd say that it is the greatest competitor to Unreal and Unity nowadays. It helps you build from the bottom up and everything that works can be easily re-used in your next games. LLM's such as ChatGPT make the workflow very agile. IMO, as I tried other engines, this has the best workflow anyways. A good chance to try it in your incoming jam! You can have a glimpse of what you can get here ;)
