I think for rough spots, the big things for me were:
-Cranes are OP. I can just spam them till the end of time and get some massive distance from them, so the storm is made irrelevant as a threat. However, this does make for a funny and memorable meme build.
-The time between storms is so long, even without the crane spam strat, you can usually keep some good distance. I think I'd have appreciated more frequent but shorter storms to keep things spookier!
-Once you've gotten to the point you've broken the resource system, and have everything producing incredibly fast, to the point there is no way you'll lose, the game still goes on for like fifteen minutes yet. Partially because of titanium rng, and partially because of having to wait for the next storm for your cannon to fire.
-The game pretty quickly starts to lag as you build bridge segments, so some optimization would be helpful. I think part of the reason the time between storms felt so long is the time is basically doubled by build lag.
-I really liked that you could upgrade many of your buildings, but by making the upgrades require you to click on each individual building and click upgrade, it means you are often better off just building a new building rather than upgrading an old one. It'd be nice if you could just pick if you wanted to build the level 1 version of a building or build the level 2 version for more resources. That way I can spam level 2 buildings like I spam the level 1 ones.
Also, all of this should be taken with a grain of salt given I really did like your game! You did a great job! I don't usually get to the end of most game jam games, but I got to the end of yours having fun the whole time.
