oh man i enjoyed this one, very polished and fun! its not everyday you come across such games on itch! one critique i have is the random difficulty spikes in some levels near the end but other than that, good game
optimization is a wide topic, its not really about one thing i cant really explain it but i can give one example, like if you have particles in your game, make sure to delete them once they dissapear because its just going to lag the game
interesting idea but the theme kinda ruins it i think, some jumps were a little too hard, you normally shouldnt do that also the movement felt kinda sluggish making it annoying when you fell
i couldnt find the last white rectangle and then i fell out of the map and couldnt reset :c but other than that i think its impressive that you managed to make this in this time, nice concept
interesting mechanics, i didnt like though that if you died, you started all the way back at the start of the first level, i thought you can bash through the enemies, maybe making them look spiky would help with that
thats a fun idea! could use a bit of juicing up though, also i kept randomly dying but thats understandable for a game jam edit: i read the description and now know why i was dying
