When I launched it just started glitching out and spamming sounds. Can't go past level screen. Had to restart game a few times before it worked. I'm pretty sure the resolution is much bigger than 48x84 pixels. Hitboxes are way too big and unfair (player dies even if they don't touch cacti at all). Would benefit to add an input buffer for jumps. Really frustrating to play because of this. Other than that it's pretty decent! Not sure if it qualifies by the rules but it's alright if these issues are fixed in future.
Thanks for taking the time to write this, I really appreciate the honest feedback! It was definitely frustrating to play before, but I just pushed an update that fixes exactly what you mentioned.
The game is now strictly locked to the real 84x48 resolution, and those unfair hitboxes are completely fixed (dying to thin air was the worst, sorry about that!). The jump input buffer is a brilliant suggestion, adding it to my to-do list right now. Thanks for playing and for the great tips!
