I liked this a lot. The gameplay is full of checks and balances. The looping bullets are genius - they allow you to set up clever reverse shots on enemies, but also turn into obstacles for you, which discourages random spamming like most twin-stick shooters. It makes for more strategic gameplay than is typical for the genre. The rewind mechanic is neat too, although it’s more situationally useful - and even that has a check in the unkillable ghosts.
It’s all very well put-together. My high score was around 50 seconds after a bit of practice. The art is really stylish as well - it would be improved a lot with music, but I understand that would be tricky with a team of one!
