the new download version is pretty laggy. Idk if it's my computer that's bad, but I played the web version (couldn't import my account). Also, light hearted suggestion to make it so that you can toggle the checkpoint respawn.
for the lag, yeah as the game gets bigger, it gets laggier, but optimisations are coming soon i think. for the toggle checkpoint respawn, just press the other keybind. Default: r = checkpoint respawn, t = full respawn. If youre used to pressing r, just switch your keybinds.
