Ok it took me a while to figure out what was going on, i actually enjoy experimenting and figuring out how a game works but in a jam environement most people wont. At first i got stuck at the 4th or 5th wave and didint understand why there was such a big power spike from my enemies.
Then i finally accepted the fact that my fleet number was a very valuable ressource, stopped trying to get one maxed out ship, armed many ships and i went smoothly towards the victory. That part was a bit confusing, the upgrade system could've been intresting but it felt totally missleading for that reason.
Why get a level 3 plasma cannon that will cause you to lose past the 4th wave when for the same cost you can equip 6 Point-blank Cannon with no cooldown and just spam 1-6 with both hand to one shot every encounter and win the game with a single ship equipped at the first wave.
I actually enjoyed it,
Point-Blank Cannon go BRRRRRRRRRRRRRR RRRR RRRR RRR
