Hey !
Quite a nice game idea.
Saddly it's harder than it should be. A step-by-step dimention travel would have been better I think because not knowing when you gonna phase trough is frustrating.
The game is good exept this. a little bit barebone maybe.
Having sound is great!
Keep at it! You worked on the game and It shows. You'll only get better :)
Cheers
Tell me if after the jam you fix the phasing problem, i'd be glad to beat the game once it's fixed ;)
