ABSOLUTELY TERRIBLE BAD LEVEL DESIGN AND BAD CONTROLS YOU SUCK

The controls are really sketchy, so it's hard to control the dog.

Pretty nice =) The sprites are really cute. and Yay! a fellow Brazilian ^-^
Some suggestions:

- From what I tested, you probably handled colisions via 1-"If player colided with enemy & animation = falling >> kill enemy // if any other animation is playing >> hit player for 1hp" or something like that.
While that's fine and saves time, it can create wonky physics. Some lateral collisions will go unpunished while some collisions that are clearly ok to the player, will result in damage reguardless, just because the wrong animation is currently playing.
The ideal is to know if the bottom of the player colided with the top of the enemy. Some engines make it easy, others don't. If your engine doesn't have something like that, you'll probably have to create an invisible object on the players' feet to detect that.

- Making the player go back to the title screen after every level is feels like a grave sin. I get it. You like your title screen XD we only want to advance the game though X3 only throw us there if we gameover. lol :)

Best of luck ^-^

Good starting point for a Platformer. Played it on mobile, performance was great. I like the sprites used for the player character and the tilemap. Enemies and UI are obviously still placeholders, but I'd suggest making sure the resolution of all your assets in the final game are consistent. Certain elements currently are higher/lower res than each other, makes the game lack visual cohesion.

Only other real suggestion is perhaps making the tap targets for the touch controls slightly larger than the input graphics themselves. I'm on a Pixel 3a, and I found myself missing the buttons rather frequently. Since you aren't looking at the buttons directly and can't find them by feel like a normal controller, having some give there tends to be helpful.

Also, hell yeah for fellow Construct user 👍

nice framework here. work on those animations (a lot) and some of the hitboxes and damage i took on level 2 made absolutely no sense whatsoever.

also stop forcing us to click start to play. that's hideous.
