Ok, this game is incredible.
The main mechanic is super cool and, despite looking deceptively simple at first, is deeper than I thought.
You can make a big line of salt and draw a circle at the end to create multiple blast, you can almost complete a circle and then wait for the ennemies to go near to close it, you can blast under your feet to fly up in the air ( :3 ).
Like, this could be made into a full game for sure.
I just wish there was more ennemy type, but it's already impressive what you achieved in such a short time.
Congrats !
