I agree with skataklysm. The aesthetics really reminded me of old-school games! The colorful hair and the way the characters move their arms give off a nostalgic vibe, like Phantasy Star! Perhaps, even to better decorate the position of things, repairing the ship should be restricted to the port, even to avoid berserker gameplay like mine was or hull orbs by a combo of dead enemies. These are very tight things to do in a jam.
I believe anyone who plays this will appreciate the the atmosphere and fun pace, as it brings back memories of games like "Pirates! Gold," where you dig for what you need, talk to characters, and take notes. I intended to play for 15 minutes but ended up playing for an hour! Haha, I loved the music; it’s very exciting, like something from Pokémon!
I’m not sure if it’s possible, but to address the feeling of dizziness (I felt it a bit when surrounded by 4 or 5 ships and trying to spin mine to escape), maybe breaking the horizontal lines with vertical waves, creating a "--^--^--^--" pattern, could help break the hypnotic continuous line. Increasing the number of deserted islands and rocks might also help focus attention. However, thinking about how I felt playing, the fact that I felt sick makes sense. Because the sea is sickening, it requires habit. For example, I started to divert my attention to the floor and when I looked back at the screen, everything was more manageable. But I think it depends a lot on each person's spirit.
I have one resolution issue. What I did was download the game and play at 1280x720, and the game adjusted itself to fullscreen. At any other resolution, it goes fullscreen but creates a ghosting effect where the button positions don’t match the mouse interactions.
Congratulations on the game; I had a lot of fun!
