Since i was asked to give extensive feedback, imma try:
1. I LOVED the game, i was lowkey glued to the screen trying to figure out which upgrades are the best for my survival. I love the concept (maybe i am just biased cuz i love tower defence games). The gameplay itself is great, and the art also fitting. I am looking forward to seeing how this game will continue. but as said, here some nitpicks:
2. In the intro, while the woman is giving instructions, the writing text sound is always on the same pitch. so it's basicly a spam of the same sfx, i'd suggest doing a random pitch value, so it feels more natural and doesn't get annoying that fast
3. Generally, i feel like the intro was way longer then it could have been, i gotta be honest, i don't think i read basicly anything there xD, but nontheless everything i needed to know was the following, so amybe you can make the intro shorter or sth:
-> survive 30 days
-> send cargoships to get more food and power
-> buy upgrades to help you survive. these upgrades are in multiple categories and server specific purposes like survival, healing, power generation, food generation, fish protection
-> there will be incomming enemies from all sides, you can click on enemies to lock your gun and kill those first, or let the gun work automaticly and shoot the closest enemies to the center (i think it worked like that, idk). there are also special enemies,
-> big orange enemies: while alive they don't attack you, but rather your returning cargo ships, so letting them stay alive will decrease your income significantly
-> camuflage: these enemies look like your returning cargoships, but when close enough it's revealed that they are actually enemy ships. The spawning of these can also be prevented via an upgrade
4. when the price was more the 4 digits, it wraped onto the next line which looked qutre bad
sp yeah, hope the feedback helps, if you need help, more feedback or playtesting i would be happy to help. love it
(also i feel like i might be the moist detailed comment XD)
