This is the guy who glazed you before Markiplier did. I got some ideas for the game to make it a little better imo :
- changing the chances for the encounters where they are in a random range like 20-25% rather then a fixed chance.
- a way to spend lunar shards after you buy all the upgrades. Maybe like a gatcha spending system similar to throwing a coin into a fountain except you're throwing lunar shards at a moon.
- changeable keybinds
- dodge-able attacks or ways to block attacks
- different enemy attack patterns like multi-hit and the possibility to attack before you (I got terrible memory so i don't remember if this is in the game or not)
- a speedrun mode to make certain animations move faster or skip repetitive scenes
- maybe something changing in the story if you kill lot of characters or play passively (yes I'm stealing this from undertale)
