I liked it, had an issue with shift as speed key - nice and smooth movement. The upgrade system was confusing/bugged, I lost but could get an upgrade.

It's a cool game. I am really sad that it has no sound. I like the "Isaac"-like tutorial.

"You have pressed shift for 5+ seconds. Do you want to turn on STICKY keys?" ... "No! I want my monster to speed up!" Good idea to add an extra dimension with the upgrades. Couldn't get so far because I am lousy at this: but I see a natural expansion to put upgrade points/bombs, powerups etc. on the field as bonus objects for one to catch/avoid.

Very nice project guys, i really love it, please check our game too and if you liked it give us a vote. Look for Road to hell and enjoy.

This was quite decent in terms of the fun. The shift key shouldn't expend energy after it is all gone.
