The feedback form glitched out for me so I'll add my feedback here.
1. The timer definitely has to be reworked, the short time makes it way too hectic with no time to actually strategize, especially late in the game when you have a lot of ships. I'd suggest instead of having 1 minute flat every turn, have 1 minute be the baseline, and add 30s per ship/planet you control.
2. I disagree with @Squonk about the game being a 'spamfest'. You actually have to consider which ship types to build and where to deploy them if you want to win efficiently. I don't know how they played the game, but randomly spamming ships would get you overrun by level 3 when the enemy starts getting a headstart.
3. I like the rock-paper-scissors system of the game a lot, but it was difficult to remember what beats what at times. I'd suggest adding a diagram that shows the ship triangle on screen rather than only showing what a specific clicked ship is strong/weak against.
4. Attacking/moving in general and the attack/move order specifically need to be explained better. I only found out after beating the game from the comments that moving exclusively happens after attacking. I'd suggest having a dedicated tutorial level, or a section in the menu where the player can read all the info about each game mechanic.
All in all the game has a lot of potential and it would definitely be cool to see it improved.
