It's a good idea but not well implemented. Most of the time, I felt like I was fighting with the controls, not the enemies. The jumping is difficult, at best, and if you can't perform a jump at the right moment, you'll be pumped full of bullets and die in seconds. This type of game needs extremely tight controls if you expect dodging to that degree. Dashing feels useless on such a small screen; I'm usually just dashing into more opponents, useless without a double dash. What is fantastic is the guns and firing, fantastic mechanics to that.
You did an excellent job on the atmosphere, themes and music. I find the visuals really appealing as well. The controls are very touchy and the game is a bit short though.
Some jumps were insanely difficult just due to control issues. Very annoying to keep trying these jumps because the angles were off, not the difficulty or timing.
It's neat at first, but after a few rounds I started to lose interest. Possibly more types of upgrades, different power-ups in game, things like that could really make this game shine.
Yeah. You should for deffi play Versus Umbra instead :D
