Hey!  M´retro I would like  advise you one thing, it´s that  a person winner never thinks  that   he will lose. so..,  look good  and  good luck.

Perdona, pero no hago juegos para ganar algo, solamente para entretener a los jugadores. Si hay algo que no te gusta, dimelo y trataré de mejorarlo.

Lo decía simplemente por socializar, ademas tu juegos son buenos, espero que ganes la jam

también quiero hacer un juego en conjunto con alguien no te gustaría hacerlo? 

No lo entendí bien, disculpa. No descarto colaboraciones, siempre que sea para alguna Jam o por diversión, aunque no dispongo de mucho tiempo. Hay mucho nivel por ahí, pero suerte igualmente.

Esta bien, yo lo hago por diversión también



Fun game, but why can he not move without jumping? Makes platforming pretty annoying.

I wanted to do something different with game mechanics to add a little more difficulty, but I'll reconsider it. Thanks

You were right. Now you can. Thanks
