I believe that adding a weapon cap was honestly the most detrimental thing you could've done. I watched someone play this game on youtube and it looked like a very fun game where I could expand my "ship" and get stronger. He played before weapon caps, and even he was struggling against the AI. My first play through I was lucky enough to get extra floatrons (I didn't realize how lucky I was. My second playthough is unplayable because I only have one and I am so immobile and small that anything is more powerful than me) However, on my first playthrough through the first wormhole I got to a normal enemy that had 6 shield, twice my size, and much stronger blocks. My weapons couldn't get through the shield let alone defend myself against an onslaught of the opponents weapons. I died on this level three times in a row because every enemy was far stronger than me through no fault of my own. I couldn't get more blocks, more weapons, or more defense. Remove the weapon cap. It's the only way for islands to fare against these random enemies.
I was heavily considering paying money for this game, since it looked like a flawless early iteration when I watched it on youtube. However, to download the game and immediately be hard caped on every single aspect I'd want to focus on, there's no enjoyment and I'm extremely disappointed :(
