the controls are really badly placed.
I mean right hand on the arrow keys (very hard to also pres ener with that hand)
left hand space
at least put shoot and jump together and move movement things to the other side (for example arrow keys for move and xz for jumping shooting)
I know that it can be costumized but please change the inital setup to something else
aside from that , good game. a bit hard at times. only made it to the jumping spider things
