absolute geniales Spiel, in einer dreier oder Vierer-Gruppe gut zu Spielen, zu zweit oder alleine leider noch so gut wie unmöglich. Aber ist mega addicting und hoffentlich kommt bald mehr Kontent (mehr karten, Uboot-typen und mehr Bomben.

I enjoyed playing the game solo and I will definitely enjoy the game with friends. I would highly recommend this game to anyone who likes submarine games. There was only on bug that I came across which was enemies getting stuck in walls; However, you are still able to attack them. good job :8bitheart:
For a small little game that just released, the quality is insane. Even the rare times you will have a bug, you will be able to go throught it. My only "complain" truly is the random crashes, which only happened once to me, meanwhile a friend never had any. The game is adrenaline inducing and keep things very balanced. Complex, but not too much. Alot to do, but not too much to do, and so on and so on. This game truly is amazing and frankly, only having 3 missions is heartbreaking because ♥♥♥♥♥♥♥♥ i want to play this game. I don't know how far the dev will take the project, but i would personally LOVE to see multiple subs to chose from, more torpedoes, components upgrades, and definitely more missions ! Everything is awesome about this game honestly. For now, a small change i would add is the option to "hold" to increase/decrease speed/turning faster coz when you play as pilot, an hour later it's really arthritis gaming. Other then that honestly it's a game close to perfection and a steal for that price. Truly a breath of fresh air in the pile of slop that is gaming today. I will rarely say this, but definitely 100% Buy the game blindly.
Great little game, we had lots of fun. Looking forward to seeing any updates. It was challenging with two players, but great gameplay and achievable with three. I'm not sure if there's enough to do with four players, so perhaps a larger sub with more jobs would be nice to have? e.g. repairs, more navigation/commander roles. Missions were okay, but only three to choose from that focused on defence against waves of enemies. More missions where there's a well-defended target to attack instead of incoming waves would be great.
