Hi, here's the feedback:
The gameplay loop is quite simple, not bad by any means and kinda casual/cozy, I have some tips on some of the other stuff:
- FOR THE VISUALS: a good practice when making pixel art games is to keep the same pixel size for all the sprites (otherwise it looses the "retro" feel and is in general not too pleasant to look at) this could significantly improve game feel, art ratings and polish. So this is a thing to keep in mind (would be better to plan the sprites to have the same size from the beginning, but if that's not possible there are things like the Unity Pixel perfect camera, or custom pixel post processing effects). In this game specifically I felt like the beach/ocean textures were too big compared to the rest.
- OTHER GAME FEEL/POLISH STUFF: The upgrade menu could be improved, I understood what all of it did, but it was a bit difficult: when dealing with a large amount of text it's imperative to keep the player's attention without overwhelming it (a wall of text is a bit intimidating sometimes), so it would be better to have also a "visual language" for UIs and other similar things, some things that help are for example icons, clever text formatting, text size that matches the importance of what it says ( Title > Subtitle > description ).
Anyways, that's all that I can think of rn, good job and good luck :)
