I uploaded a new version that has manual save/load support. Lower left of the screen has a download button that just saves as "savefile.json" (or (1), (2), ... (n) if you download repeatedly). Load button gives a simple dialog where you can browse to the savefile.json file and it loads that save game as soon as you've selected a valid file. I did also correct the "try to jump" bug - it wasn't properly checking for wall tiles after all.
The .json load seems to work great. Seems like a better approach for my setup. (I left the itch.io cookie exception though - now I don't have to solve a captcha every time I want to comment.)
Impressive scale to this update. I like "big worlds" and this fits the bill - dunno how many maps I haven't even been to yet.
Trying to come up with a word for the difficulty. For now I'll use fiendish, although it seems like a better word is on the tip of my tongue.
Wow, this was a monster update. Dash, bomb mode, secret level(s)... I played for 2 hours straight and was a little stiff when I quit. On the verge of being addictive. I should go back and count the screens. Still haven't been to all of them.
Gameplay is impressive for an html5 game. What it eventually needs IMO is controls for tablet/phone. Dunno if that is feasible though.
