I like its music and option for either sound or effects there, also clicking gets a different pic appearing fitting to dis/enable those sections.
That "incremental"-tag originally let me notice that your game exists and not sure if the title or preview-pic somehow caught my attention, possibly just the method of playing this game on browser? While I generally like levelling-typed games too.
I just headed in-game, while that astroid (click, hold, move ...like drag&dropping a link) even works for e.g. this graphic, maybe I'm just too curious about tiny features, just thought feedbacking this info. Maybe not marking text could quite prevent users from copying images, maybe same for hovering over words will currently change my pointer from default to "I"-icon, which is used for html-input-tags, etc.
"starmap"-object sounds awesome with space ink animation, also "show the way to someplace cool" possibly including a missing single gap, I guess & maybe "some cool place" instead? btw: when buying it, but just taking it and not wanting to read closer info ...would be cool to get more options like: okay/nope. Same if something would get revealed in addition, what if I'm planning to examine it later? There's no "back"-button yet.
I also like how every object moves when the player being idle, also when starting the game and that planet's "face expression" changed from wow to ow.
Cool background/text-colours, graphical animation and I like its story. The itch-description's hint about progress-saving is informative too.
Derek's gym: stronger to 80atk (at its first lv) or pump-health to 100hp. uhm, if I'm using the last upgrade (btw: I had Derek beaten by enemies in a dungeon, having -7hp, while using the ressources for trading them against health it's 100/100 now. Still in dungeon he's at the same status: reviving by using some stardust), why isn't he alive with his full-health now?
Could that slot-machine probably refer to its percent/chance of success - would be awesome.
in-game shop: upgrading hp-potion effect, does it somehow downgrade automatically after getting it from 50 to 60?
I adore that paper which reveals some additional stuff (without spoilering too much info for new players) & I like the screenshots about this game.
