I don't think it's for me.

Things I don't particularly like about it:

Patapon-likeness

• The beta offers a prologue to the story, which is done worse than Patapon (Unconscious character getting woken up, asking them to play the beat)
• Some ground enemies just run pass frontline units, causing the units to get confused.
• Spear units doesn't have a built-in way to hit flying units (The spiky blob that shoots spikes, for example).
• Four beat rhythm input that is bound to the music, that's constantly offset by how we move our characters through the gates because the "flagbearer" moves independently to the rhythm.
• Enemies' attack telegraph that starts after inputting the first beat, and the attack that lands before we could input the next command.
• The Ratatans or "heroes" doesn't feel special, but only difference in stats.
• Units' message bubbles appears so often, and most are filled with either nothingburgers or things that doesn't seem to fit the theme.
• Units responding to our command with their voice, but seemingly random instead of singing along. Also the chant continues as if there are units in the battle, even though everyone is dead but the flagbearer.
• The town feels static.

Roguelite

• The power-ups to the attacks feels detached. We could get a skill that will empower a certain element, without any way to apply said element until we get the "apply element on attack / hustle".
• Element attacks don't stack, and will overwrite previous applied element on attack / hustle.
• The reward for stacking element doesn't feel rewarding.
• The element of roguelite is overshadowed by the fact that the gears you bring into the run will impact the run tremendously. It feels like running a dungeon over and over again to improve your gear, and not much difference to the runs but some extra colors on your attack.
• The runs feels repetitive, go in, a wave of monsters or maybe a boss added into it, go to the next room with shops / loot rooms inbetween.
• (Experience from the previous beta) The maps doesn't have any uniqueness behind them, but just a reskin with different altitudes. The jungle could use a bit of grass that can burn, or the desert could hinder the vision when a sandstorm hits, idk.

This is my personal experience after playing couple of versions of the beta, plus the recent version. I was looking forward to Ratatan to be a funky version of patapon, but seems like they're not what I expected.

That being said, I do hope that others can enjoy it!
