Nice platforming! You also coded slopes, very impressive! The animations are smooth and it feels very fluid to move the character around. The graphics are charming and nice HUD as well! I have some suggestions to enhance a little bit what is already in the game:
- Make the enemies get into a knockback state when they get hit, by making an (one frame) animation and setting a recoil speed to them. Of course, don't forget to make them recover after a while;
- Add sound effects! (hit, jump, steps, breaking barrels and boxes, sword slash). I know it's an extra work, but it makes a lot of difference, don't underestimate it! In case you can't make your own, you can look for sound effects in public domain, there are sites (such as https://freesound.org/ ) that have a public domain tag. Then, you can mix or edit them with a software called Audacity (it's surprisingly easy to use for effects);
That's it! By the way, nice neon afterimage effect on the protagonist! Well done!
