hi
nice arcade action.
Be critical! well.
Please don't hate me, I can imagine how much work you have put into this game.
I like the game and have played worse in the app store and after 20 min of gameplay and here are my findings.
Graphics: it looks professional and pixel art looks suitable for this kind of game.
Movement: maybe because of keyboard control. The fly movement feels fine, but when the monkey lands then platform the movement feels clunky( not smooth) and it is hard to adjust the money on a small platform without falling off.
Animation: I did not notice it at first that monkey and enemies have no walk animation and then it was hard not to see
music: did not mind, maybe shorten the loop
collectable: maybe have other collectable other than just kill an enemy for points or rocket( was not sure what collecting it did). could try combo points for hitting/ kill enemies within a set time.
unlocks: when something was unlocked it went by too fast for me to notice it, maybe pause, go into slow motion or have items screen for all unlocks( yes more work ).
Enemies: it would nice that if you land on an enemy it kills them or pushes them aside. it looked a bit odd when the monkey and enemy shared the same space.
Pause Screen: it was unclear at first that numbers were for adjusting the sound level
Laser part: what do the white guys do. I was unsure why sometimes I when through a laser and other times got killed by them.
good job
keep it up.
