Visuals
1 ... (main menu) without hp bar & text animation:
1.1 . example: lets do simple zoom text tween/interpolation between 0.8-1.2.
2 ... (game): I love this effect when player hits ground
3 ... try to remove all repetitive tile patterns -> how to fix it? lets say 10 tiles for same center tile type
Design
1 ... why is left side out of map visible (is this intended)?
2 ... interesting gravity invert mechanics -> I love it
3 ... add check points (I hate been bad in game -> then from LV3 go again in tutorial and do all again)
Controls
1 ... very responsive -> they are already giving feeling to player of character control
Gameplay
1 ... player jump into toxic poison -> monster jumps after player -> player re-spawns -> monster stays dead (is this intended)?
Sound
1 ... There is no sound -> add sound effect & OST/BG sound (or its a bug?)
Bugs
1 ... eye monsters sees player -> monster jumps into toxin -> player move forward (check Gameplay 1.)
2 ... monster standing on player hat & do 0 dmg -> animation is bugged that it seems like monster is flying.
