The difficulty spike murdered my brain cells but the mechanism is pretty clever and has a lot of room for clever levels. I thought this would pair well with a 3-star rating system which shows the minimum moves to achieve three stars and players might go beyond that for even better sense of achievement

A very good take on the theme, very great level design, really had my 2 braincells thinking xD, Overall 5/5 awesome work :)

a fun and unique puzzler!

Really hit the sweet spot for me in terms of being simple to understand while gradually increasing the challenge. Great escalation of mechanics :)

Top idea, was quite challenging and the simple art style gave me nostalgia for the old impossible rage games

neat idea that was really improved by the deleting blocks, they made for fun puzzles, I think you could have got away with no move timer and it would have still been a good challenge. I liked how the grey blocks were necessary pieces and obstacles to be removed, that was clever

Really cool and original Idea, pretty challenging too.  Had fun playing this, my only suggestion would be maybe a ranking system showing how well you did on each map based on moves left 

Fun puzzles.  The last two puzzles seemed a little odd to me.  They weren't bad really, they just had a lot going on but the solutions seemed to ignore most of the puzzle and in the case of level 9 I finished with a ton of extra moves.

I was also a little unsure about how it chose which block to connect when there were multiple available blocks.  But it seems that there were very few opportunities for this to happen, which was probably a clever choice on your part.  If you are going to make more levels, particularly with this mechanic involved in the solution I think it would be nice if this were explained or made clear from the interface.

Nice concept! The use of limited moves makes it a fun challenge. I'd say a reset key could have helped in those times when I knew I'd messed up, apart from that I enjoyed it!

Really good concept, the difficulty ramping up was really smooth. Very well thought through. Great work!

i wish they announced qub 2 at E3 this year, this game definitely deserves a sequel

Very original and cool concept. The puzzles were also really fun. With improved graphics and audio, this would be a fantastic game!

(I'm also a solo dev :D)

Clever puzzle! Easy to pick up, so perfect for a game jam! Good job!
