This game is freakin awesome! I think my only criticism is it would be kinda nice to maybe have some extra buttons to select the items (1-4 maybe?) and have Z be a dedicated jump button, as it is right now it's a tad hard to control. Also I was confused at first because I thought you would have to COLLECT items, but I figured it out easily enough I guess. Really cool!
(Also idk what engine you made this in, but an update to use controllers would make this just about perfect)
