Cool game! Really liked the overall aesthetic, the colors work really well. Also liked the music, especially since it felt very thematic withe the phone noises. The game itself was fun too, and it felt easy to understand the overall mechanics. Some things i noticed in no particular order: - The AI making moves by moving its own cursor is a really nice touch and made it easy to follow what the ai did on its move; although if the game was longer the animation would have probably started to fell too slow for me, tough i did win before it really became an issue for me - Having limited options is interesting and lead to some fun moments, but also felt bad at times: i especially got unlucky with not getting any options to move my units for a long time, which lead to me not really being able to make any interesting decisions in the early game, maybe some sort of system were options are pick from categories would help (or always having a basic move option maybe?) - The Y2K move felt very powerful and hard to plan around since you never know when your opponent is going to be offered it, making me very reluctant to use clamshells, especially since they didn't feel that powerful compared to the risk; my instinct is that the game would have been better off without it, but maybe clamshells would lack a counter then, hard to say (maybe a less powerful version, or one where you need to sacrifice something additional in exchange?) - The roaming option also felt a lot stringer then a lot of the other moves, though maybe not to the point of being overpowered; but i still think it could probably use a downside to make it a more nuanced choice.
Making statements about balancing is ofcourse hard without lots of plaything various changes, but aside from the things mentioned above i felt you did a really good job. Would have been interesting to play against a more powerful ai opponent to see how that feels (but making a very strong ai is a bit out of scope for a jam ofc.). Great game overall, i had a fun time!
