Recently I published Predicate and now a free demo of the game, including the first 2 bosses, is available here: https://boboto.itch.io/predicate-demo
If you're interested in the game try the demo and buy the full version here: https://boboto.itch.io/predicate
Predicate is a challenging and unique bullet-hell with colour and simple design being a major focus. Crush enemies with your tail or shoot them down while dodging swaths of projectiles and attack patterns.
