I played this with Plabs and BricksParts, and I know one of the devs showed up in the chat. I had vtubestudio and discord issues, so had to bail early. We talked about boss fights, difficulty spikes, and a few other things that are apparently all in development.
Graphics are cute, music is great, and OH BOY does it get chaotic after level 5. Still, a lot of fun, even with the little ring toss mini game. That's cute! Controls are easy and even in a "trial-by-fire" method, it still is easy to figure out, generally. Frank was a bit confusing, but we figured out how to use him a bit more as we played. He can definitely be an asset! This has a lot of solid potential and am looking forward to the full version!
Vod can be found here. Gameplay takes a while to get in to, as we were trying to get stream together to work, fully starting around 40:00 in
