This is one of those games where I feel quite overwhelmed reading the tutorial, and then when the game starts it immediately clicks ^^
It's pretty fun, and while the concept wasn't exactly original to me (I've seen a few jam games from this jam having former "you"'s reenact what you did before), what I liked here is, that your former selfes where actually fairly dodgeable still. They aren't too quick or unreadable to react, and you don't have to memorize everything you did, which is very nice.
I like the music and the sound effects too, though one big nitpick: The sound effects are *way* too loud in comparison to the music. If the music is on a decent volume, the sfx hurt my ears. When the sfx are on a decent volume, I can hardly hear the music.
The art looked nice and gave the game some flair, but I wished it had a bit more narrative because that can quite change a game.
Controlling wise, I wasn't too impressed, it felt a tad boring that all you could do was move and shoot normal shots in 4 directions. Some different shot types, buffs, anything would have made it more interesting imo.
Nonetheless, the game was great and quite addicting, good job : )
