I can see that! Might have to grab this...even if I still haven't beaten Cave Story...(stuck in the ants area, tank boss too hard qwq)
The game has lots of charm and I think you'd have fun with it. Much like Cave Story (and metroidvanias in general) there might be parts where you might feel stuck and unsure of what to do... but we also created a handy walkthrough to help out in case you do!
