Hi, i couldnt pass the first spiky ball because im bad i guess hahah, BUT! the game looks really good, nice pixel job. i think the game can improve a LOT if you make some little adjustments like, increase the time in the air between jumps, slower fall and making bigger Safe zones, to give the player places to breath hahaha, also i think the music is cool but is very loud.
The things to improve are details and a little balance, but the game is solid and a lot of fun to play, the art is really cool i loved the pterodactil in the main screen also the colour palette.
Amazing work!
