tip for 8x8 2-4: Once you get stuck start guessing since there seem to be many solutions. Was stuck for about 10 minutes then started guessing and took me about a minute to finish.
This is a great great game but it's definitely lacking compared to Upgrade Complete 2. The amount of Art in this game is insane, I think more effort should have been put into new features and the gameplay. I know the gameplay is supposed to be simplistic but it required almost zero skill. It was a fun 20 minute game but just that. Still giving the game a 5/5 but I am disappointed.
Welp I refreshed my page and I got set back about a day. Definitely not playing this game anymore if i don't get my progress back. And I emailed the developer earlier today. 5/5 game if the save properly worked.
Great game in general but the obstacles are a bit arbitrary. In general you're going too fast to ovoid the obstacles and when you are going really fast sometimes you hit an obstacle and it turns you all the way upside down.
This game had great potential. The ending was very anticlimactic. I didn't even know that I had reached the core, I thought once I got through the yellow layer I would reach the end of the game or I would get some reward, but nope the yellow layer just goes on forever. Great game until the end 4/5
