This was both fun and frustrating - I got 9 keys, but could not make it past the last part. I'd like to see some faster movements, and maybe some checkpoints, but overall it was a good platformer and I liked that I had to figure out how to do some things on my own. Kudos on using RMMV for this too, I love seeing non-rpg games made with this engine! Good job, I hope you keep working on this, I'd like to see more in the future!
