I quite enjoyed the submarine atmosphere the game is going for. I also quite liked the submarine and drone models, they look futuristic as heck, would be even better if it's textured though. The gameplay is a bit on the simpler side, where it's entirely possible just to let the drones do the hard work (AUTOPLAY!!!!!!) while drinking tea carefreely. I also managed to reach all max upgrades in just day 3, hopefully I am not experiencing the game wrongly. Not sure if the game has an ending, though. I quit after getting my second cup of tea with 1500 points to spare.

Other things I like:

• Drones AI works reliably and is cool to watch them destroying enemies
• The burst mechanic is really cool, shame to see it not being required to play the game
• Small and lovely upgrade system
• A home base and there are enter and exit animations as well

Suggestions:

• The scenery would definitely need decorations. Some rocks/water bubbles/fish/other vehicles/other bases in the distance would be nice
• The side cannon barrage felt a bit useless, and the effect looks like an above water attack rather than an underwater one
• Some more enemy variety would be great
• Docking mechanic is a nice touch, though using buttons on the top left corner felt very out of place and hard to use. Some indicators of which drone is docked would also be great
