Sure. I think the horn gesture is a good idea. I also have planned to make attacks animations for the player, but since it's a platformer, for now you can use the jump on enemy mechanic to kill it (this is why the enemy death animation look like that). For the missing tiles, this was purely intended (I did the tiles, and still have it) but didn't want to use it to keep that retro limitation style. However I think adding it is just a plus so I'll add them back. This is also why I added AA in every tiles corner, because in older games, tiles couldn't have transparency, and I love that render even if it can look dirty in some places. Thanks for the feedback, I will soon update the files, stay tuned !
Edit : I can also show you a sneak peak of the next update (this is just a few tiles, and some might change)
