This is a great idea for a game, I love the graffiti effects from the different color paints and that they remain in place after respawning! Very creative all around.  My critique is that the player is very sluggish, I wish the movement speed was faster as I did get frustrated and didn't complete the game entirely.  I may have encountered a bug as well, is the red paint supposed to destroy the thorns?  It did not on my playthrough.  The player design is cool, reminds me of the Mind Flayer enemies from DnD and Demons Souls!

Super creative! The idea is really awesome~ Keep working on it for sure :D  Great job!!

Very cool mechanik with painting the wall, I just felt a little quirky to controll it.

An interesting concept for a character and their associated mechanics.

PROS:

• Painting the background and manipulating the world at large is actually a super cool way to let players know where they've been and functionally tell their own story.
• Quick-swapping between paint types was easy and practical.
• The game didn't rush a lot of challenges at you early on to let you get better at controlling your character.

CRITIQUE:

• I definitely got lost within the level design. The checkpoint markers kind of help, but without having a clear goal of "go here" to associate with the map that they show I can't get too much info out of them.
• I found myself wanting an eraser very early on. That may be a later upgrade, but I didn't make it far enough to tell.
• There are a lot of doorways that are very blocked by enemies constantly throwing projectiles. This may be just to deter me from using them and force me to find other ways around, but I opened the door with the yellow paint that I'd just acquired and I could see a clear path around the enemy so I felt compelled to try that several times even though I'd take enough damage to die and respawn soon after passing the door.
