This is a really interesting demake of the traditional RTS genre. I did used to watch some SC2 back in the day and the impressive micro skills that were on display were always mesmerizing to watch. I've tried my best to keep up but some of these levels are a bit too tough for my measly RTS skills haha. Though I do say I really like the upgrade system you implemented! I also enjoy that enemy projectiles in particular are actual projectiles with a flight time that can be dodged if you are quick enough.
The handmade SFX and low poly style really gave me TABS vibes. It was a really cute game. Overall great job making an interesting twist on an established genre.
