Pretty nice game, id recommend adding a rating system at the end of each level, probably based on the time spent finishing the levels, it would really fit the style of the game. One thing i would also recommend is using a different perspective because i cant explain with words how confusing it is playing this on a keyboard. Another thing i dont like which maybe in some cases is a good thing is that when you get the blocks in a corner, there is no way you can get them out except restarting the level. Some things i do like are the background music which is a little repetitive, also the walking sound effect can get annoying because it gets played every step i take. I also like the design a lot and that you can change it by changing your character, which i recommend adding a unlocking system for (example: for 10 stars you get a new design) and maybe add a sound effect for when you finish a level (also pls make it easier im not proud at all to admit i couldnt get past level 5)
