The game can be fun, but the fact that a mere slip-up can undo so much effort put into a level kinda ruins some of the fun. Here's some changes that can be really useful:
Dialogue Box Speed: Text should reveal faster! Also, tapping the interact key should be made more obvious for signs (and tapping it should just immediately make the text appear) Also, there's so much more room you could take up with the dialogue! Just showing 1 line is a waste when you have room for 2-3 lines!
Respawn mechanics: Instead of death resetting the level, the player mushroom just immediately respawns, additionally, this can help implement checkpoint mechanics into the game to spice up future levels
Camera Panning: In order for me to understand what I am doing, I needed to move my shrooms to opposite ends of the screen to read the level, if I can just move the camera, it would make planning so much easier.
Level Select: IDK what level number I gave up on, so it would be nice to know my progress
Audio improvements: I want SFX so I feel like the game is properly reacting to my input, I also want more variety in the BGM (plus a way to disable it cause it can get tiresome listening to the same track on loop)
Level readability: Background tiles make it hard to tell what is ground and what is not
Implement these changes and I'll provide those 2 missing stars.
