Nice game, cool concept! Clean and crispy vector art!
I playtested for a little bit, the game works and runs great, I'm only a little pedantic when playtesting games (I playtest games as I do for mine that now has a long list of known issues XD) this is what I noticed (apart from that 8 point goal stuff, maybe you already also noticed these):
- in the tutorial section: there is "poin" instead of "point"
- I would normalize the speed of the diagonal movement (diagonal movement is faster than horizontal-vertical one, I suspect you add two movements without normalizing the resulting vector)
- the player flickers a little bit when it reaches max speed
- approach the crystals on the bottom from the top (ending near the bottom border between two crystals, and to work you need to go down with a little bit of the player collision box intersecting a side of the crystal) and then try to move left and right: that movement is restricted (seem by collision boxes of the crystal )
- Sometimes I got a point (and a crystal started shooting) but I don't know why (doing nothing), it happened with bottom crystals while I was testing point 3. (maybe an enemy spawned inside a crystal?)
Anyways, great job!
