You should be incredibly proud for this being your first release! I really enjoyed your approach of "Nothing Can Go Wrong" as an assurance rather than as an ominous warning. Switching positions instead of restarting in the same place as a checkpoint was a really cool way to distribute power ups intermittently rather than clearly linearly.
I was really looking forward to seeing what happened after rejoining myself, so I'll be sure to keep an eye out for any further development you do! That experience was downright buttery.
