Almost finished playing this cute game, really promising, just a couple small thoughts about how to tell players what's going on. I experimented for like 20 minutes to make sure just loosing health does not actually cost you any money, also I just found out thru another coment that releasing the line doesn't make u lose the fish and is required to get the bigger ones which I wasn't aware of. also with both these things in mind, it's actually pretty easy to beat most of the game by just fishing a bit, only buing upgrades and just going back whenever the poisoned gas starts (or even later) to avoid loosing so much health that you die. also from what I've experienced every pattern of what dangers happen is the same with it raining, then being poisonous then raining again, I never made it further than that and am very close to unlocking the third lock. to maybe make the game a bit more challenging over time you could make it mandatory to open the locks before being able to get the next level of upgrades and vice versa and then also make the game be harder/mix up the cycle of dangerous events with each unlocked element, that way the game keeps casual players as me from just grinding on the lower levels without any action happening. still thanks a lot for making this sweet and fun little game, 9.5/10 already recommended to some friends
