A game where you fight entrophy, i very much like it, you really get into playing the swarm and each decision has its cost.
The enemies are well thought out, the small turrets makes the clock tick so that stalling is not an option, the shield prevents rushing and the cannons are the bane of inattentive players. The nature of the game means that Lancheste's law is more prevalent than in any other, kill many enemies at the start and the run is a piece of cake, mess up the beggining and time will erase your fleet; a fix could be regeneration from both sides, gaining ships with time and turrets growing on unnocupied places, making the player adapt on the fly, avoid focusing one side and making the end-game challenging as well.
The controls could be faster, the slowness of the cursor means that sometimes you have to waste a lot of time just getting where you need to be and others getting your ships killed because you wont ever be able to get there. But speed aside the game is fair, you need to make calculated decisions of when and where to shoot, there is no way to brute force your way to a win.
Theme, is any RTS a good thematic entry for this jam? After all they always have a Only one commander, you have Only one boss to fight but it never feels like it, the focus is always on the swarm not the cursor, the focus is on the specific enemies, not on the boss as a whole. So it technicallly fits the theme but not in spirit.
Originality, this game is truly original, the mechanics, the controls and the fantasy it delivers is not only unique but excellent.
I loved this game, i dont think is the most fitting for the jam but nonetheless is a great entry. Please make a tutorial to get confortable at first, create more content (levels, enemies,etc) and launch this game, a mobile version would sell for sure.
